Right guard Laurent Duvernay-Tardif, who graduated from medical school at McGill University last spring, was activated from injured reserve on Tuesday. In a corresponding move, safety Ron Parker was waived.
Durvernay-Tardif suffered a fractured fibula earlier this season and has been on injured reserve since Week 6.
Parker, a five-year starter for Kansas City, played in 15 games this season for K.C. with 14 starts, compiling 77 tackles and two interceptions.
