Reason For Kyle Boller Signing: Raiders QB Gradkowski To Have Surgery On Injured Pectoral Muscle

On Thursday evening the Raiders signed former QB Kyle Boller. It was a bit of an odd move considering they already had three mediocre (or worse) quarterbacks on the roster.

Now we find out the reason he was signed, courtesy PFT's Mike Florio.

So why did the Raiders sign quarterback Kyle Boller on Thursday?  Though they possibly were considering the move anyway, a specific need arose on Wednesday, when (per a league source) quarterback Bruce Gradkowski tore a pectoral muscle while lifting weights.

Apparently, he was bench pressing at the time (and JaMarcus Russell just said, "That's why I don't lift weights"). He'll have surgery on Friday.

He won't be throwing for about a month after the surgery.

It's good timing considering it is the offseason, but you've gotta wonder how he'll respond from the injury. The best spot on the Raiders is the No. 2 quarterback. You know JaMarcus Russell will perform terribly and eventually be benched.
