Early in the first half of the Buffalo Bills' 27-20 loss to the New York Jets, cornerback Leodis McKelvin went down with a hamstring injury and did not return. The move prompted the Bills to shuffle their injury-ravaged secondary around, playing safety Aaron Williams as a cornerback and using four safeties in dime looks with just two corners on the field.

The man stuck in the middle of the movement: cornerback Justin Rogers. A three-week starter with Stephon Gilmore out of the lineup - and a player that entered the season as, at best, the fourth cornerback on the roster - Rogers was the only true cornerback to log more than 50 percent of the defensive snaps on Sunday. To put things exceedingly kindly, he had a forgettable performance.

We made a speed run through NFL Game Rewind so you didn't have to, and came away with this: the Jets threw to receivers covered by Rogers nine times on Sunday. One of those plays was an incompletion that nonetheless yielded the Jets 22 yards when Rogers was flagged for pass interference. On the other eight throws, Jets receivers caught six of them - for 254 yards and two touchdowns.

One more time: Justin Rogers gave up six catches, 254 receiving yards, two touchdowns and 22 penalty yards in yesterday's loss.

Gilmore is still wearing a brace on his surgically repaired wrist, though he has begun doing conditioning work during weekly practices. We should know later today what the prognosis on McKelvin's hamstring is. Ron Brooks is out indefinitely with a foot injury. The Baltimore Ravens, Buffalo's Week 4 opponents, are positively salivating looking at the Bills' current depth chart in the defensive backfield.
