ORCHARD PARK, NY - Before Rex Ryan could put Sunday's 28-25 loss at Miami in the past, he had to address a few other losses first.

Safety Aaron Williams and running back LeSean McCoy are now the two main concerns after both left Sunday's game. Williams left after taking a shot to the head from Dolphins' wide receiver Jarvis Landry. McCoy's exit came from pain in his hamstring, the same one he injured earlier in the week.

"He got clearance from our medical personnel," Rex Ryan said during his Monday press conference. "That’s a variety of tests, tons of tests. Also, the player needs to sign off on it. So, it’s not just the medical staff going, 'Hey, you’re going out there.' So, LeSean wanted to play. He felt like he was ready to play. And then, before the game, we took him to pregame and he was running routes at full speed and bursting."

McCoy injured his hamstring during practice on Wednesday that forced him to leave early. He missed the entire session on Thursday but participated in practice on Friday. McCoy finished the game with just eight carries for eleven yards before taking himself out of the game in the second half.

"We thought he was ready to go," Ryan said. "100 percent ready to go. That’s why we played him. Will we do the same again? If every box is checked, then yes. If any box is not checked, then no way are we going to play him. And we’ve said that from day one about any player."

As for Williams, he was taken to the hospital after the game for a CT scan and MRI. He traveled home with the team but is still being evaluated for a head and neck injury.

"The reason he went to the hospital was because that is where they have those machines, but right now, just so you know, he is walking around and you know he is talking to people and is in our meetings today," Ryan explained.

Ryan also said they will err on the side of caution with Williams, a wise decision given he suffered a neck injury last season that caused him to miss time.
