Allen came in with 11:22 remaining in the third, one possession after starter Nathan Peterman threw his second interception of the game, setting up a 1-yard touchdown run for the Ravens.
Peterman completed 5 of 18 passes for just 24 yards and two interceptions while taking three sacks before he was replaced. The Bills had gained just 33 yards on 20 plays without a first down in the first half. It was Peterman's third career start after he went 11 of 24 for 123 yards, one touchdown and five interceptions in two starts as a rookie fifth-round pick in 2017.
Allen, 22, finished 6 of 15 for 74 yards, while also taking three sacks, as the Bills lost 47-3. He added 26 yards on four carries as a rusher and led the Bills to their only score, a 12-play, 46-yard drive for a 35-yard field goal.
Buffalo coach Sean McDermott was vague when asked about the team's quarterback situation after the game, declining to say who would start in Week 2 and reiterating that the offensive struggles were caused by many issues.
"I'm going to look at everything," McDermott said. "It's too early to go one way or the other. Going to look at everything and be objective and make sure we put ourselves in a position to win games."
Asked specifically about Peterman's play, McDermott said he needed to review the film and see how the QB's supporting staff played before making an assessment.
"It's not just one guy," McDermott said. "It's a full, a total team effort there."
On Allen, McDermott offered a few more detailed observations.
"I thought he made some pretty decisive throws in there, into some tight windows," McDermott said. "He used his feet at times as well. I thought he had pretty good command of the huddle and the offense at the line of scrimmage. So other than that, generally speaking, we'll go back and look at the film and evaluate."
The Bills traded up five spots in the first round of the April draft to take Allen. He was given a chance to compete for the starting job in the preseason, but an ugly outing against the Cincinnati Bengals (6 of 12, 34 yards, five sacks took) hurt his chances.
Peterman was named the starter after a strong preseason, and free agent signee AJ McCarron was traded to the Oakland Raiders.
