Buffalo Bills QB Allen leaves with elbow injury

Buffalo Bills rookie quarterback Josh Allen left Sunday's game against the Houston Texans with a right (throwing) elbow injury.

Allen was sandwiched by Jadeveon Clowney and Whitney Mercilus after a throw late in the third quarter, and Mercilus' helmet appeared to hit his elbow. He went down and grabbed at his right arm. After staying in for one play, he was replaced by Nathan Peterman and ruled questionable to return by the team.

Allen was later seen sitting on the bench without a helmet and holding his right arm. He went 10 for 17 for 84 yards with no touchdowns or interceptions, along with four carries for 20 yards, before departing.

Peterman led the Bills to a go-ahead touchdown on his first full possession, hitting Zay Jones for a 16-yard score.

Peterman was the team's opening-day starter but was benched in the third quarter of a 47-3 loss in Week 1 after completing just 5 of 18 passes for 24 yards and two interceptions.

Allen entered Sunday with a 2-2 record as a starter since Peterman's benching.
