(WGR 550) -- The twists of the Buffalo Bills quarterback position over the past eight days has taken another dramatic turn. This time around, it's news no player would want to hear.
According to Tim Graham of The Buffalo News, the concussion sustained by Bills quarterback Kevin Kolb could be of the career-ending variety. Graham also reports from a league source that the team is approaching the situation with that possibility in mind.
Kolb started his second consecutive preseason game for Buffalo, but had to leave the contest with concussion-like symptoms after just his second drive. On a scramble, Kolb picked up eight yards on a 3rd-and-5 and slid to the turf to try and avoid contact.
While he was sliding down however, a defender trailing him connected with the back of Kolb's head. It took the quarterback half a second longer to get back up, but he did and ran back over to his offense. Kolb completed the final four plays of the drive.
This is the third reported concussion Kolb has suffered since 2010, having it happen once while playing for the Philadelphia Eagles and then again with the Arizona Cardinals. He is only 28 years old.
Graham's report and the team's two transactions on Sunday evening fall in line with one another. The team announced they've signed quarterback Matt Leinart, and a league source told WGR Sports Radio 550 that the team has acquired quarterback Thad Lewis from Detroit for linebacker Chris White.
Further muddying the situation, the Bills are also dealing with the knee injury to first-round pick EJ Manuel. After all the transactions, the team now has five signal callers on the roster.
