Buffalo Bills running back Karlos Williams left Sunday's season finale early with a knee injury. He has been ruled out for the rest of the game, bringing an abrupt end to his stellar rookie season.
The injury occurred on Williams' two-yard rushing touchdown in the second quarter, which gave the Bills a 13-0 lead over the New York Jets. Williams was hit prior to the goal line, and ended up twisting his body to extend the ball over the stripe for the score.
Mike Gillislee will handle the bulk of the Bills' carries for the remainder of the game. Boobie Dixon will also pinch in as needed.
Williams, a fifth-round pick out of Florida State last spring, missed long stretches of time earlier this season with a concussion and then a shoulder ailment. Despite his production in 2015 - he finishes the year with 517 rushing yards, 96 receiving yards, and nine total touchdowns, which ties a record for scores in a season by a Bills rookie (Lee Evans) - the Bills have to be concerned about Williams' durability heading into the 2016 season, especially given his running style.
