Buffalo Bills training camp live updates: Day 14, Cleveland Browns scrimmage

A bout of thunderstorms passed through the Pittsford area earlier on Tuesday afternoon, but the Buffalo Bills and the Cleveland Browns persevered, holding their second joint training camp practice at St. John Fisher on Tuesday evening, albeit one that was cut short due to the threat of more storms.

Even the abbreviated practice session could not prevent the injury bug from continuing to gnaw players out of action for the Bills. A potentially (but hopefully not) serious hamstring issue for LeSean McCoy stole the headlines, but several more players missed the practice, with Rex Ryan spending most of his time after practice updating reporters on the health and status of many of his biggest-name players.

Here's the rundown of everything you need to know from camp last night.

Hey, at least Kyle is back

#Bills HC Rex Ryan: LeSean McCoy has a hamstring injury. The hamstring is in tact, not off the bone. We're getting an MRI on it

#Bills HC Rex Ryan: We don't know if it's a pulled hamstring for McCoy, but we're hoping it's just a strain.

#Bills HC Rex Ryan: Watkins was a precautionary hold out from tonight's practice. Woods felt tight tonight as well and sat out.

Rex said Harvin had PRP injection after his hip soreness "didn’t respond" the way the Bills wanted. Wants to return for DET game if not PIT.

Rex Ryan says Karlos Williams "had a procedure" and will miss at least two weeks.

When asked about RB Karlos Williams’ procedure, Rex Ryan smiled, called it a "sensitive thing" and later pointed toward his lower abdomen.

Plucky Cordy

Cordy Glenn and Phil Taylor go at it after play before whistles break it up. Browns tried stripping ball from Hill a bit after the play.

Another small scuffle erupts. Cordy Glenn again involved. Bills, Browns are in 11-on-11 period; ball carriers are going to ground.
