Turns out Tyrod Taylor wasn't the only Buffalo Bills quarterback injured in Saturday night's preseason loss to the Baltimore Ravens.  On Sunday Bills coach Sean McDermott revealed that back-up quarterback T J Yates is also in concussion protocol.

Yates apparently was injured late in the game while the Bills were desperately trying to drive for the winning touchdown.  The coach didn't know exactly when and how he was injured, but because of the way those types of injuries are handled it means the Bills are down to one healthy quarterback heading into their preseason finale at home Thursday night against the Detroit Lions.

We already knew that Tyrod Taylor was injured during the Bills second offensive series when he hit the back of his head on the turf during a sack.  He was helped to the sidelines, then taken to the locker room and later diagnosed with a concussion.

So now the question for the Bills is what they'll do while both Taylor and Yates are out.  McDermott said that he and general manager Brandon Beane are scanning the NFL for a player who might fit into the type of offense the Bills are running.  With final cutdowns around the league not scheduled to be made until after Thursday it might tough for the Bills to find what they're looking for.

In the meantime, rookie Nathan Peterman will be seeing a lot of work during practice this week and on Thursday night against the Lions.
