Brian Asamoah Injury: Won't return due to knee injury

Asamoah (knee) has been ruled out for the rest of Thursday's game against the Ravens.

Asamoah injured his left knee during the first half of Thursday's game, and it is severe enough for the fourth-year linebacker to be sidelined for the rest of the contest. His absence won't impact the Bengals' defense, as he has played solely on special teams this season.
