During Buffalo's press conference Thursday, head coach Sean McDermott did not rule out Trubisky (knee) for the Bills' regular-season opener against the Cardinals on Sept. 8, Alec White of the team's official site reports.

Trubisky injured his knee in Saturday's preseason game against the Steelers. Initial reports indicated that the injury would sideline the 2017 first-round quarterback for multiple weeks, but McDermott seemed to indicate Thursday that Trubisky has a chance at suiting up for Week 1. If not, Ben DiNucci -- who Buffalo signed on Aug. 12 after Shane Buechele landed on IR with a neck injury -- would serve as the backup quarterback behind Josh Allen to start the season, while Anthony Brown would fill in as the emergency QB.
