Buffalo Bills quarterback Josh Allen exited the game with a right arm injury against the Houston Texans.

Allen was sandwiched between two Houston defenders after competing a 39-yard pass to Kelvin Benjamin in the third quarter. Bills coach Sean McDermott was visibly upset that a late hit penalty wasn't called.

Bills coach Sean McDermott hasn’t ruled out giving Nathan Peterman what would be his fourth career start on Sunday against the Chargers. (Peterman won last year’s snow globe game against the Colts, throwing 10 passes and completing five.) Via Joe Buscaglia of WKBW, McDermott has yet to decide on a starter for Week Two. Asked how he could justify going with Peterman again, McDermott said the blame for Sunday’s 47-3 blowout spreads widely to everyone on the team.

The Bills don't seem ready to throw Allen to the fire yet, the story said, possibly because their schedule to start is a pretty tough one against quality defenses. The story also said the Bills line is struggling and can't buy time for any QB.

Nathan Peterman has been named our starting QB!

The Bills will go with Peterman over the rookie Allen. Peterman has impressed in camp, according to reports. Even so, at this point neither Peterman nor Allen are expected to rank very high week-to-week and will be considered more like QB3 options.

Bills QB AJ McCarron is expected to return to practice soon, per source. So another twist to the Bills’ QB competition.

Apparently McCarron does not have a broken collarbone as reports said following last week's game. The Bills did say recently McCarron was getting a second opinion and that tests were inconclusive. It has been a strange and complicated QB competition and rotation, according to those who follow the team. Allen will start this week's game for the Bills and was looking to be the favorite to be the team's starter for Week 1 when McCarron was going to miss time.

Bills HC Sean McDermott said Josh Allen will work with the first-team offense in Monday’s practice and Nathan Peterman will run the second-team offense.

On Sunday, Peterman led the first team and Allen the second team. McDermott said it’s a rotation, Rodak continued in his tweet. The injury to McCarron (shoulder) seems more likely to open the door for Allen at this point, but the Bills QB rotation so far in camp has been a strange one, according to those who follow the team.

Buffalo Bills quarterback AJ McCarron is getting a second opinion to determine the severity of an injury to his throwing shoulder.

HC Sean McDermott said he could not provide an update on McCarron because tests on his right shoulder were not “totally conclusive.” Other reports say it was a broken collarbone. The injury opens the door for Allen to perhaps win the starting job.

The injuries suffered by Bills quarterbacks Nathan Peterman and AJ McCarron at Sunday’s practice were not serious.

Both Peterman and McCarron are back on the field Monday morning, according to reporters on the scene.

Peterman was the starter for the Bills’ preseason opener. McCarron seems likely to start this week, given that he and Peterman have split time with the starters throughout training camp, although head coach Sean McDermott has not announced a starter.

Buffalo Bills quarterbacks AJ McCarron and Nathan Peterman both appeared to be banged up late in Sunday's practice.

McCarron was seen limping after a play during an 11-on-11 drill ended in what would have been a sack. The play was whistled dead because defenders are not allowed to make contact with quarterbacks during practice.

Peterman appeared to be hurt on his final play during a live-action drill at the goal line to end practice. After being tripped while attempting a handoff and falling on his right arm, Peterman spoke to trainers and later was seen testing his throwing arm.

The Bills return to practice Monday in advance of their next preseason game on Friday against the Cleveland Browns. Coach Sean McDermott declined Sunday to name a starting quarterback for that game. Allen saw time with both the first- and second-team units, the story said.

According to Joe Buscaglia of WKBW, AJ McCarron is taking first-team quarterback reps for the second day in a row. It is the first time either he or Nathan Peterman has done so.

This indicates that McCarron is ahead of both Peterman and rookie Josh Allen to be the Bills starter. The Bills have no incentive to rush their rookie quarterback, but he will likely get into the mix before Peterman does. We project both McCarron and Allen for over 200 pass attempts this season.

The Bills wide receiver corps is one of the league’s thinner ones heading into training camp, which would seem to bode well for 2017 second-round pick Zay Jones‘ chances of seeing a lot of playing time once September rolls around.

While that may be the case, General Manager Brandon Beane made it clear last week that Jones won’t be guaranteed anything this season.

“He’s not just going to necessarily go right to the top of the line,” Beane said during an appearance on WGR 550, via NewYorkUpstate.com. “He’ll have to earn his way. Part of that will just be just getting his feel. He’s only played with Nathan Peterman. He has not got to play with Josh Allen or AJ McCarron yet. So that bond there will just have to form.”

Jones had a quiet rookie season dealing with a shoulder injury. As the story pointed out, it's not an overwhelming list of WRs, so Jones certainly has a chance to make his mark and earn a key role in the offense.
