The Bills finished the third game of the preseason and don't have a starting quarterback determined.
After the Bills' 26-13 loss to the Cincinnati Bengals on Sunday, coach Sean McDermott was not ready to name a starter, saying he would evaluate the tape.
He also declined to provide a timetable for when he would name a starter with the Bills' season opener in Baltimore two weeks away.
Rookie Josh Allen was walked off the field by athletic trainers after his head seemed to hit the turf hard on a hit by the Bengals' Carlos Dunlap just before halftime. He was cleared to return after being evaluated for a head injury, the Bills said.
Nathan Peterman came into the game as his replacement for the remainder of the Bills' final series. Peterman then played the second half. He finished 16-for-21 for 200 yards and a touchdown.
“Nathan Peterman has shown consistency throughout the preseason," McDermott said. "I’ve watched him develop and grow, which is encouraging to see.”
Allen was battered in the first half, getting sacked five times. He finished 6-for-12 for 34 yards.
"We have to make sure we're helping Josh Allen, and not beating ourselves with penalties," McDermott said. Overall, the Bills were penalized 13 times for 125 yards.
It is the second consecutive week the starting quarterback was injured working behind the Bills' starting offensive line. AJ McCarron was hurt last week.
McDermott said McCarron remains an option when healthy. He could take part in practice this week.
"He continues to have a good camp," McDermott said. "Once he's healthy and ready to go he'll get back in the mix."
