Status of Bills' Ragland uncertain after left knee injury

PITTSFORD, N.Y. (AP) The status of Buffalo Bills rookie linebacker Reggie Ragland is uncertain after initial tests were inconclusive for his left knee injury.

Bills coach Rex Ryan provided the update before the team's evening practice on Saturday. Ryan said the Bills must wait for the swelling in Ragland's knee to go down in order to get a clear diagnosis.

Ragland suffered the injury on a non-contact play near the end of the team's Friday practice. He was going after the ball carrier on a run play before pulling up and going to the ground. Ragland eventually was able to walk to the locker room under his own power.

The Bills have been counting on an immediate impact from Ragland after selecting him 41st overall in the draft. Buffalo is also without first-round pick Shaq Lawson, who underwent shoulder surgery in the spring.

Ryan said the team will bring several linebackers in for a tryout on Sunday. Buffalo is down to three healthy inside linebackers.
