Monitoring Bills' health against Bucs

The Buffalo Bills will hold their final walk-through of training camp Friday at St. John Fisher College before heading back to the Buffalo area Saturday.

Here is a look at which players may not suit up Saturday afternoon against the Tampa Bay Buccaneers:

Sammy Watkins: The rookie receiver hasn't been cleared by team doctors after bruising his ribs last Saturday against the Pittsburgh Steelers. At this point, it makes sense to hold out Watkins until the regular season.

Leodis McKelvin: Early in the week, all signs pointed to McKelvin returning from hip surgery to make his preseason debut Saturday. That changed when he left Wednesday's practice with a groin injury. He missed Thursday's practice and isn't likely to play Saturday.

Tony Moeaki: The clock is ticking on Moeaki, who hasn't been able to fully return from a hamstring injury. He played in the fourth quarter of the preseason game in Carolina before sitting out last week's game in Pittsburgh. He didn't participate in team drills in practice this week and isn't likely to play Saturday. His roster spot could depend on his ability to get healthy next week.

Jonathan Meeks: The second-year safety remained out of practice this week with a neck injury.

Bobby Felder: The third-year cornerback sat out practice this week with a groin injury.

Mario Butler: The cornerback, who is a long-shot to make the final roster, did not practice this week due to an ankle injury.
