Cleveland Browns quarterback Brian Hoyer left Thursday's game against the Buffalo Bills with a right knee injury.

The former third-string quarterback and native of suburban Cleveland, Hoyer, who filled in for an injured Brandon Weeden and engineered back- to-back victories, exited early in the first quarter with a knee injury.

Hoyer was hurt while sliding at the end of a scramble. He broke free along the right sideline and picked up a first down, but was hit from behind by Bills linebacker Kiko Alonso and his legs bent awkwardly underneath him.

Hoyer is scheduled to undergo an MRI Friday.

"I don't want to be premature," Browns head coach Rob Chudzinski said. "Let's find out what the status is and see what the MRI says. Anytime you lose a guy who's done what he's done, it's disappointing. But let's see what the MRI says."
