Mitchell Trubisky's knee injury raises concerns about Bills quarterback depth

The Bills have a problem if they end up having a problem with starting quarterback Josh Allen.

Backup Mitchell Trubisky, who returned to Buffalo after a two-year stint with the Steelers, suffered a knee injury upon his return to Pittsburgh and is out “week to week,” according to the team.

Over USA TodayTrubisky was seen training in a large brace on his left legStabilizing the knee. We haven't been given any details other than “week to week”; the Bills need to have someone ready to go behind Allen starting Week 1.

While it's considered bad form and possibly a curse in some circles to say something like “If Josh Allen gets hurt,” we've had a lot of starting quarterbacks get injured this past year. The Bills need a veteran backup with extensive game experience, which is why they brought back Trubisky.

Right now, it's Ben DiNucci and Anthony Brown. DiNucci has three regular season appearances and one start — four years ago. Brown has two regular season appearances and one start in 2022.

While there aren't many good options, the roster has been whittled down to 53 in four days. And the Bills will certainly take a close look and maybe even trade someone before then. If Trubisky is going to miss several weeks of the regular season, the Bills would be taking a big risk by playing with a backup player who has limited game experience.
