We have an update on Reggie Ragland’s injury. Kind of.

Ian Rapoport of NFL Network tweeted the following on Bills’ rookie linebacker:

#Bills LB Reggie Ragland, who injured his knee, had an inconclusive MRI, source said. He's seeing more docs and getting 2nd opinion Monday. — Ian Rapoport (@RapSheet) August 6, 2016

Ragland left practice Friday after what Chris Brown of the team’s official website said he ‘‘appeared to step on the foot of the ball carrier causing his left knee to buckle.’’

David J. Chao, an orthopedist and former NFL head team doctor, sent out a few tweets on this report.

Contrary to public opinion, MRI is often inconclusive.

Why I say no substitute for exam in hands of good orthopod. https://t.co/amHL9jebXt — David J. Chao, MD (@ProFootballDoc) August 6, 2016

Not necessarily out of the woods yet but better than a definitive need for IR. https://t.co/d44HBu2Tw3 — David J. Chao, MD (@ProFootballDoc) August 6, 2016

Looks like we’ll have to wait until Monday -- at the earliest — to get a definitive word on the severity of Ragland’s injury.
