Kansas City Chiefs safety Tyrann Mathieu will play in the AFC Championship Game on Sunday against the visiting Cincinnati Bengals.
The Chiefs announced Sunday that they had removed Mathieu's injury designation, clearing him to play.
Mathieu suffered a concussion in Kansas City's win over the Buffalo Bills last week, but he had no setbacks in the concussion protocol this week.
Mathieu, who was picked to play in the Pro Bowl, led the Chiefs in interceptions with three this season and returned one for a touchdown.
A nine-year NFL veteran out of LSU, Mathieu, 29, is in his third season with the Chiefs, following stops with the Houston Texans and Arizona Cardinals.
With Mathieu in the fold, Kansas City has made the past two Super Bowls, winning one, and now has an opportunity for a third straight appearance.
