Brian Asamoah: Everything you need to know

Asamoah (knee) was placed on the injured reserve list Monday. The fourth-year pro from Oklahoma sustained a knee injury in the Bengals' Week 13 win over the Ravens, and it now appears serious enough to land him on IR. Asamoah has appeared in just four games for Cincinnati this season, failing to record a stat across 58 special-teams snaps. He'll now be forced to miss at least the team's next four games, with his earliest possible return coming in the Week 18 matchup against the Browns.

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.

The Bengals signed Asamoah from the practice squad to the active roster Monday. Asamoah was elevated off the practice squad for one game with Cincinnati earlier this season, when he played 19 snaps on special teams in Week 9 versus Chicago. He figures to contribute in a similar capacity for the team down the stretch, beginning Sunday on the road against Pittsburgh.
