The Bills began preparation for next week's game against the Miami Dolphins with questions at quarterback, a recurring theme for Buffalo the past month.
Head coach Sean McDermott said Tyrod Taylor has made progress over the past couple of days but his status remains day-to-day. He was inactive Sunday against the Indianapolis Colts after suffering a knee injury against New England the week prior.
Nathan Peterman is still in concussion protocol after what appeared to be a helmet-to-helmet impact in the third quarter Sunday. He was hit by linebacker Antonio Morrison while diving for a first down.
Before the Colts game, McDermott said Taylor would be the starter if both quarterbacks were healthy. He reaffirmed that statement for Miami but complimented Peterman's performance in snowy and low-visibility conditions.
"For a young player, (he was) into the game, had good control and command of the huddle and the situations," McDermott said. "He did some good things that were baked into our win, some of them seen, some of them unseen."
Joe Webb, who has spent most of the season on special teams, is the only remaining quarterback on the roster. He passed infrequently while under center against Indianapolis, completing two of his six attempts. 34 of his 35 yards came on his overtime pass to Deonte Thompson.
If Webb starts Sunday, it will be his first start at quarterback since the Wild Card round of the 2012 playoffs.
"We’ll see what Coach McDermott has in store," Webb said after Sunday's victory. "I will always be ready if my number’s called. If that be the case, then I’m prepared for it."
McDermott said he'll discuss the possibility of bringing in another quarterback this week with general manager Brandon Beane, but currently feels comfortable with the players already at One Bills Drive. He didn't clarify whether that meant he was comfortable with either Taylor and Peterman's chance of returning or rolling with Webb.
"With the medical reports that we've gotten to this point, which is still early, and Brandon and I still coming off of the game from yesterday, we're still going through our process," McDermott said. "For right now, where we are in our week, I'm confident in what we've got."
If Taylor and Peterman are unavailable, tight end Logan Thomas would be the emergency backup. Thomas started 47 games at quarterback over four years with Virginia Tech, amassing 9,003 yards, 52 touchdowns and 39 interceptions.
He played in two games with the Arizona Cardinals in 2014, throwing for 81 yards and a touchdown, and isn't unaware of the Bills' systems. Offensive coordinator Rick Dennison said Thomas has been in meetings and has thrown some this season after practices.
