Mitchell Trubisky

Bills GM Brandon Beane told reporters Wednesday that the team is “cautiously optimistic” that Mitchell Trubisky won’t need to be placed on injured reserve.

Beane did also caution that they won’t know for sure until they see Trubisky practice, so it can’t be ruled out. The 30-year-old backup injured his knee during the early portion of camp. If he’s unable to go, the Bills will likely go with Mike White as the backup to Josh Allen after White was signed to the practice squad by Buffalo on Tuesday.
