LANDOVER, Md. – Buffalo quarterback Kevin Kolb was treated for concussion-like symptoms after getting kneed in the back of the helmet in the Bills preseason game against Washington.
Kolb was hurt at the end of an 8-yard scramble in the first quarter. He remained in the game for four more plays, until the drive ended with a 2-yard touchdown run by C.J. Spiller.
Washington won 30-7.
Kolb has been competing for the starting job with first-round pick EJ Manuel, but Manuel hurt his left knee in the Bills previous game and is out for the rest of the preseason.
With both Manuel and Kolb hurt, undrafted rookie Jeff Tuel entered the game on the next series.
Kolb has suffered at least two concussions over six NFL seasons.
