Minnesota Vikings quarterback Teddy Bridgewater suffered a concussion after taking a blow to the head from St. Louis Rams cornerback Lamarcus Joyner during the Vikings' 21-18 overtime win Sunday.

Joyner was penalized for the vicious hit, which occurred after Bridgewater had given himself up with a slide early in the fourth quarter.

Shaun Hill took over at quarterback while Bridgewater went to the locker room to be evaluated for a concussion. He'll now, of course, have to go through the league's protocol, but his Week 10 status is up in the air. The Vikings travel to Oakland in Week 10.

For what it’s worth, rookie Stefon Diggs was running with the first-team offense in the three-receiver set during the open part of practice this morning. But we should also note that the media only gets to see the first few minutes of practice. Probably because we’d report things like this.

Near the end of the open part of practice, Diggs was lined up with Mike Wallace and Jarius Wright. They ran routes near the goal line with quarterback Teddy Bridgewater at quarterback.

For those keeping track, Diggs ran with the starters on Wednesday, ran behind Charles Johnson on Thursday and was back with the starters on Friday. Whether or not he plays starter's snaps in Week 7, only OC Norv Turner knows. We feel comfortable ranking Diggs as a WR4 with upside, but owners counting on him this week should be aware of his floor. It's hard to believe that the Vikings would send him back to the bench after his quality play in the last two games, but stranger things have happened.

Of Adrian Peterson's 10 carries on Monday night, six came with Teddy Bridgewater under center. Four were with Bridgewater in the shotgun, about 4-5 yards behind the center with Peterson standing next to him. Peterson gained just 7 yards on those four handoffs, as opposed to 24 yards on six carries in an I-formation. And while it was only four handoffs, it was also 40 percent of the workload for Peterson on his first night back, after he'd taken just 60 carries in the shotgun in the last two years.

"You really just need to be more patient, allow the pulling guard to get on his block and hit it up in there," he said Monday night. "Those are the ones I felt like I was kind of hesitant on. I really wanted to hit like I was coming out of the I-formation."

Said coach Mike Zimmer on Tuesday: "I don't think he looked tentative. I think he was aggressive, trying to get to the hole and maybe trying to get to it a little bit too fast at times."

A big part of Peterson's game has been starting 7 yards deep in the backfield, taking a handoff and hitting the line at full speed. He's going to be asked to change that approach with Bridgewater, who was under center only about 34 percent of the time last year, and there's inevitably going to be an adjustment period for Peterson. But even in the limited success the Vikings had with Peterson in the shotgun Monday night, there were hints of why they want to play that way.

The Vikings were in the shotgun or pistol about 65 percent of the time after Teddy Bridgewater took over as the starting QB in Week 4 last season -- the 13th-most in the league, according to ESPN Stats & Information -- and their 565 shotgun snaps in that time were only 210 less than they had in 2012 and 2013 combined.

Adrian Peterson, of course, was in the backfield both of those seasons, and has yet to play his first game with Bridgewater at quarterback. In those two seasons, Peterson ran just 40 times out of the shotgun, or one fewer than Christian Ponder. Matt Asiata and Jerick McKinnon, on the other hand, logged a combined 114 carries out of the shotgun last season.

"I think the things we're doing out of the shotgun, he's very comfortable with, and getting more comfortable," Turner said. "We're going to give him a good dose of the things he does best and has done best his entire career. We're going to try to spread the field a little bit and do some things to give him more space."

There's little doubt the offense will require something of an adjustment for Peterson, who's made a career out of lining up seven yards deep in the backfield and hitting the line of scrimmage with a healthy fury, the story said. But between the Vikings having enough of Peterson's staples in the playbook and giving the running back enough practice snaps to adjust, offensive coordinator Norv Turner thinks Peterson will be fine with an offense that's a little more spread out. It should only help Peterson as long as Bridgewater and the receivers and prove to be a legit passing threat. It will be a lot for defenses to account for.

The hype machine has yet to start cranking for Minnesota Vikings wide receiver Charles Johnson. When it comes to the team's offensive skill positions, running back Adrian Peterson, quarterback Teddy Bridgewater and a handful of other receivers have all generated more discussion than Johnson.

However, Johnson's 10-yard touchdown catch in a preseason win over the Oakland Raiders on Saturday served as a subtle reminder of what he brings to Minnesota's offense.

"You talk about that touchdown catch he had today with the defensive back all over his shoulders," Bridgewater said, per ESPN's Ben Goessling. "Charles, he’s a big, physical guy. He helps out in the run game with his blocking for the running backs and it showed tonight in the passing game in just the first half -- not even the entire first half, but the first quarter. He showed that he’s going to be big for us this year."

At 6-foot-2 and 215 pounds, Johnson hides in a cast of receivers that includes Mike Wallace, Cordarrelle Patterson and rookie sensation Stefon Diggs, among others. He is listed as the starting "WR2," opposite Wallace, on the Vikings' preseason depth chart, the story said. Johnson is 34th on our WR list and hasn't really been that big of a secret in drafts this season. Teams are taking him in the middle rounds because he's got a lot of positive press since the end of last season.

Charles Johnson isn't one of the three Vikings-drafted receivers on the roster, nor is he the prized offseason acquisition.

But since Johnson was plucked off the Cleveland Browns' practice squad nearly a year ago, he's been one of Teddy Bridgewater's favorite targets in a receiver room that has been recently bolstered with developing young talent, like fifth-round pick Stefon Diggs, and a new face in Mike Wallace.

Johnson led the team with 40 receiving yards on four catches, including a 10-yard touchdown in the second quarter of the Vikings' 20-12 preseason win over the Oakland Raiders on Saturday night.

"Charles continues to make plays," coach Mike Zimmer said. "Catches the ball, runs good routes. The touchdown he caught, I thought the guy was grabbing the heck out of him the whole way."

After the Vikings jettisoned Jerome Simpson last fall, Johnson joined the Vikings after spending the 2013 season rehabbing a torn ACL under then-Browns offensive coordinator Norv Turner. Less than two months later, Johnson became the Vikings' starting split end over 29th-overall pick Cordarrelle Patterson and turned 25 catches into 415 yards as Bridgewater's go-to target in the rookie quarterback's best stretch of play in December, the story added. We see potential for Johnson and think he could at least put up low-end WR3 numbers, like he did from Week 11 on last year when he finished as WR31 in that span. We rank him 39th on our WR list, and he's getting some mid-round draft attention.

These days, the Vikings list Teddy Bridgewater at 215 pounds, and he looks noticeably more solid. The offseason plan was for him to beef up.

"There was a set amount, a set weight limit for me coming into training camp, which is 215," Bridgewater said Wednesday at training camp. "I was able to put on some weight but most of it was muscle. I'm trying to make sure that I'm building myself up to withstand some hits that I'm going to take throughout the year and withstand the long season that's ahead of us."

It's good to hear that Bridgewater is packing muscle on his relatively slight frame. It can only help. The acquisition of Mike Wallace is good news for Bridgewater, who averaged a solid 15.0 FP after his Week 10 bye. Those are QB2-type numbers, so with a year under his belt and Wallace (and a healthy Kyle Rudolph?) in the mix, Bridgewater should be a good QB2 with QB1-type upside if everything breaks his way. The return of Adrian Peterson can only help the offense as a whole.

Andrew Krammer of 1500 ESPN listed Charles Johnson and Cordarrelle Patterson as the most intriguing position battle in Vikings camp:

Johnson-Patterson is the most intriguing position battle, for the split end spot. Johnson showed enough to keep the job through offseason work, but a 29th-overall pick in Patterson will get plenty of chances to earn his job back. There's no question about Patterson's ability. With the ball, he's a threat to score anywhere on the field. In order to get the ball in less predictable spots, he needs to be in sync with Teddy Bridgewater. Inconsistency in his routes didn't allow chemistry to build as he's still learning the nuances of the position. Patterson had four playbooks in his last four years of football, and some consistency on that end could help him take the next step.

We favor Johnson in this "battle," due to his production down the stretch last season. Johnson started playing significant snaps in Week 11, and over the final seven games of the season, he averaged 3.6 catches for 59 yards and 0.29 touchdowns. He was the #31 fantasy receiver in that span.
