The Buffalo Bills aren't sure what they have behind Josh Allen at quarterback.

Sean McDermott said after Buffalo's preseason opener that there is an open competition for the No. 2 quarterback job.

Kyle Allen got the start against the Indianapolis Colts.

Allen completed eight of 15 passes for 122 yards, no touchdowns, and one interception, while Matt Barkley completed 14 of 15 passes for 172 yards and two touchdowns, in four drives.

They're both on one-year deals. Barkley is getting $1.25 million, and Allen is making $1.232 million. Barkley has $235,000 guaranteed; Allen gets $350,000 guaranteed.
