Bills WR Jordan Matthews will undergo thumb surgery and is expected to miss at least a month.

Matthews finally got on the scoreboard with a TD this week, too. Jones looks to be Buffalo's top receiver and it should mean Clay continues to be a force in the passing game at TE.

Tyrod Taylor went to the locker room with trainers and is in the concussion protocol.

Taylor's head bounced off the turf upon falling hard after being sacked in the BIlls preseason game against Baltimore.

Taylor was a 4for4 favorite in 2016 until Sammy Watkins’ injury and he still produced top 8 numbers with Watkins in and out of the lineup. He was a top 10 quarterback on a per game basis in 2015, so he has now produced starter-caliber numbers in two straight seasons. However, with the Bills trading Sammy Watkins, his ceiling is lower now, and if he is in the concussion protocol, his status for Week 1 will now need to be monitored.

Anquan Boldin's stint with the Bills didn't last long. Less than two weeks after signing a one-year deal with the Bills, Boldin is retiring.

The news was first reported on Sunday night by ESPN's Jim Trotter. Shortly after, Boldin released a statement through Trotter.

It's a pretty big blow to the Bills who are dealing with a banged up Jordan Matthews as perhaps their top receiver. After that it's Zay Jones, a rookie. Andre Holmes, Rod Streater, Brandon Tate and Philly Brown round out the team's WRs.

Joe Buscaglia of WKBW:

It feels like almost on a daily basis now, I’m writing that “this was Zay Jones' best practice to date,” and then the next day, he raises the bar just a bit more. That’s the type of improvement you hope to see from young players in their first training camp and rookie year, and it’s what we saw yet again on Wednesday. What really stood out was his route running ability, and where some receivers loaf through breakdowns ahead of their cuts, Jones has seemingly thrived. It’s within the intricacies of route running that players that aren’t the most physically gifted to win with speed, can win all game long. That was Stevie Johnson’s game when he was working as the Bills’ top target, and it’s what kept him as a productive player until injuries derailed his career. Jones has that type of ability, and he’s clearly getting open against cornerbacks during training camp. Plus, they’re training him as both an outside receiver and in the slot. Now, the big questions are this: Can he do it during games, and eventually, in the regular season? That’s a bridge we’ll have to cross when the opportunities present themselves, but Jones has done just about as well as you could have wanted him to through the first six days of training camp. To me, he is winning the battle for the second wide receiver spot as it stands today.

Jones was the first receiver taken in the second round and the fourth wideout off the board overall. The Bills have been -- and should continue to be -- a run-oriented team, but there is plenty of opportunity for targets in Buffalo. The Rams signed Robert Woods away, and he averaged 86 targets in his four seasons with the Bills. Jones is 6-foot-2, ran a 4.45 40-yard dash, and generally tested well across the board at the Combine. He was a standout at the Senior Bowl, and showed the ability to run a full route tree in practice. Throw in the second-best drop percentage of his class and you can see why he’s a good bet to contribute immediately in Buffalo. If Sammy Watkins is active and healthy, fantasy owners will likely be using Jones only on a matchup basis, but if Watkins misses time, the rookie could quickly see WR1-type targets.

Bills WR Sammy Watkins rehab appears to be on schedule, as he was able to participate in a few team drills before the Bills wrapped up their spring practices. With six weeks between mandatory minicamp and start of training camp, Watkins should be close to 100 percent when camp starts Thursday.

“Credit to Sammy, credit to our training staff and the way he’s attacked the rehab with them," coach Sean McDermott said at that time, according to the Bills' official website. "That has to continue, though. This is one step in that process of getting Sammy back to where he needs to be and where we need him to be."

It's fair to say the Bills still need convincing that will happen. That was evidenced by the decision not to pick up Watkins' fifth-year contract option.

The Bills may reduce his practice time and limit appearances in preseason games. The team has taken steps this offseason to prepare for what might happen if Watkins isn't healthy. The team drafted Zay Jones in the second round, and is expected to host veteran Anquan Boldin on a free-agent visit Monday. Of course, neither of those players would be expected to put up the kind of numbers Watkins is capable of when healthy, the story said.

The early signs were encouraging from Bills second-round pick Zay Jones. But Jones sustained an injury in Tuesday’s OTA practice and did not participate Wednesday and again today (Thursday).

The Bills have confirmed that Jones sustained a knee injury and is week to week. It has been described as a knee sprain.

Jones has a great opportunity to see big snaps immediately, but missing multiple weeks due injury is obviously not a good thing.
