LAWRENCE, Kan. (AP) – Top playmaker Tony Pierson will miss the rest of the season for Kansas because of recurring symptoms from a concussion that he sustained against Texas Tech last month.

Jayhawks coach Charlie Weis said Tuesday that “a healthy Tony is critical to the success of our program, but not at the risk of Tony.”

Pierson missed most of four games after he sustained a concussion while getting tackled Oct. 5. He returned Nov. 9 at Oklahoma State, but took another big hit in a win over West Virginia on Saturday that ended the Jayhawks’ 27-game Big 12 losing streak.

Pierson is the Jayhawks’ leading receiver with 24 catches for 333 yards and a touchdown. He’s also run for 163 yards.

Kansas visits Iowa State on Saturday before hosting Kansas State to finish the season.
