Jacksonville Jaguars lost their top wide receiver due to a knee injury Sunday against the Texans.

Wide receiver Allen Robinson injured his left knee on a 15-yard reception during the first quarter at NRG Stadium.

Robinson has been ruled out for the remainder of the game which means Lee, Westbrook and Hurns will see a bigger role. That would also be the case should Robinson need to miss future time.

Rookie running back Leonard Fournette expects to be ready for Jacksonville's season opener. So does receiver Marqise Lee. Fournette and Lee spoke Saturday for the first time since being sidelined by injuries a week ago and expressed confidence they would play in the Sept. 10 opener at Houston.

"I'm very confident," Fournette said. "There's nothing to worry about."

The fourth overall pick in the NFL draft was shut down last Sunday with a left foot injury that coach Doug Marrone called a "nagging issue." Fournette said he didn't know what caused the pain. "I've never had a foot or toe injury or anything like that," he said. "But they're doing a great job with rehabbing. I think it's going pretty good."

Fournette missed parts of his junior season at LSU because of a sprained left ankle, but he said his latest injury has nothing to do with that setback.

Lee fell to the ground during a passing drill last Sunday and immediately grabbed his right leg. Lee's lower leg was immobilized before he was taken off the field on a cart. He was diagnosed with a badly sprained ankle.

Lee spent several days in a walking boot and used a crutch, but ditched those in the last few days. He said the next step is to start running again.

"I'm pretty confident I'll be fine," Lee said. "I can't make a move without the trainers and the coaches. It's their decision, but I'm going to go ahead and jump in: I think I'll be fine by Game 1. Doing everything possible to be ready by Game 1. That's all I really can control. So I'm just going to do that."

Fournette is the odds-on favorite to lead all rookie running backs in fantasy points. The last eight running backs drafted in the top 10 that saw at least 200 carries (in their rookie season) averaged 308 touches for 1484 yards and 9.8 touchdowns, for a PPR average of 240 fantasy points. The Jaguars are going to run Fournette early and often. VP of Football Operations Tom Coughlin said that the team drafted Fournette “to put the ball in the end zone.”

Lee emerged in his third season as the #2 receiving threat in Jacksonville, turning 105 targets into 63 catches for 851 yards and three touchdowns en route to a #42 finish in PPR formats. He could progress into the top 30 if he continues to improve as a receiver, but the Jaguars have drafted (Leonard Fournette) with the intent to run the ball more, and that may negatively impact Lee’s workload.

"Chad Henne going into game with first-team offense. Pre-planned we're told," was the tweet from the Florida Times-Union.

Blake Bortles, a constant Twitter goat through training camp with constant reporters of practice interceptions, could have had at least one picked Thursday night against Tampa Bay, before finishing with only 65 yards on 8-of-13 passing.

Chad Henne entered the game late in the 2nd quarter with the starters.

The fact that Henne was even out there with the starters in the second preseason game shows Blake Bortles' job is not safe under a new coaching staff. If you watched the game, Bortles was worse than his pedestrian numbers even show, at one time underthrowing a wide open Allen Robinson downfield. Meanwhile, Henne had two passes for would-be touchdowns dropped by his receivers, including Robinson. However, Robinson's eight first half targets are certainly notable.

Ian Rapoport of NFL Network reports that Jaguars receiver Marqise Lee suffered a high-ankle sprain and may not be ready for Week 1.

Lee had a career-high 63 catches for 851 yards and three touchdowns last season, and the Jaguars thought that with Lee joining Allen Robinson, Allen Hurns, Rashad Greene and rookie Dede Westbrook, they had a strong group of receivers. Now they’ll need that depth.

That’s worse news than the Jaguars were initially hoping for, the story said. The early indications were that he wouldn’t miss much time after hurting his right ankle in Sunday’s practice. It should mean more reps for Greene and Westbrook.

Jaguars WR Marquise Lee suffered what appeared to be a non-contact injury to his lower leg Sunday at practice. An air cast was brought over initially but not used before Lee was carried over to a cart with no weight put on his leg.

UPDATE: From NFL Network's Ian Rappoport: "Jaguars WR Marqise Lee, who was carted off today, did not suffer a serious injury, source said. Looked a lot worse than it was."

That's good news for Lee who started to get more involed last season. Lee was the WR32 in the second half of last season in PPR points per game. It's important to remember new head coach Doug Marrone was one of the most run-heavy playcallers in the league during his time in Buffalo.

It took 12 weeks, but Jacksonville Jaguars receiver Allen Robinson finally couldn't stop himself.

Angry at another instance in which what appeared to be an obvious pass interference penalty wasn't called in the fourth quarter of Sunday's loss to Denver, Robinson yanked off his helmet and yelled at an official. He was hit with an unsportsmanlike conduct penalty and went to the sideline seething.

"That's not really me, but it's been frustrating," Robinson said after the 20-10 loss at EverBank Field. "It's been frustrating, and not the amazing officiating but just all around. Sometimes you've got to let it out, and that happened.

"I've never been this frustrated playing the game of football in my life."

As the story said, and as fantasy owners know, it's understandable. Robinson had a breakout season in 2015, catching 80 passes for 1,400 yards and a franchise-record 14 touchdowns while making the Pro Bowl. He's had a much harder time in 2016. He's on pace to catch nearly the same number of passes but finish with more than 500 fewer yards.

Jags WR Allen Hurns had his right ankle rolled up on from behind by his teammate Allen Robinson while he was blocking on a WR screen. Hurns returned to the field after missing a short period of time, but was later ruled out after suffering a concussion.

Hurns has certainly seen better days. Obviously the concussion is the bigger issue since Hurns was able to come back after hurting his ankle.
