LeSean McCoy gives Bills a scare, after giving them halftime lead

Bills running back LeSean McCoy was off to a great start, but Bills fans are now holding their breath, as the centerpiece of their offense just had to be helped off the field.

McCoy went down late in the second quarter, and trainers were checking out his right knee. But moments later, he was up and making cuts on the sideline, seemingly dodging a bullet.

He has 11 carries for 106 yards and two touchdowns in the first half, as the Bills lead 17-13.

The Bills have other worries at the moment, as wide receiver Robert Woods just went to the locker room with athletic trainers, after being shaken up earlier.
