Bills CB McKelvin escorted off after feeling ill

Buffalo Bills cornerback Leodis McKelvin missed the final hour of practice after being escorted into a cooling tent because he felt ill.

Coach Chan Gailey said the player was taken into the tent as a precaution and held out for the rest of the two-hour session Friday, two days into training camp.

With a wet towel on his head, McKelvin walked without assistance while being escorted off the field by a trainer. The mid-afternoon practice was held under a mostly cloud-less sky with temperatures in the low 80s.

Gailey said trainers will monitor McKelvin to determine whether he can resume practicing on Saturday.

Gailey ruled out conditioning as being a factor by saying the team's 2008 first-round draft pick reported to camp in great shape.
