Indianapolis Colts tight end Dwayne Allen was diagnosed with a sprained ankle and is considered week to week, a source told NFL Network's Ian Rapoport.

Allen suffered the injury during the first quarter of Sunday's loss to the Houston Texans. Prior to suffering the injury, Allen caught one pass for nine yards.

Jack Doyle and Erik Swoope are expected to gain more snaps in Allen's absence.

Allen caught 18 passes for 192 yards and two touchdowns this season.
