Kansas City Chiefs hold tryouts for four linebackers amid injury concerns

The Kansas City Chiefs conducted tryouts for four linebackers on Thursday, September 17, 2026. This decision follows the placement of linebacker Cooper McDonald on injured reserve due to an injury that will sideline him for at least four games. The tryouts included free agents Marte Mapu, Dominic DeLuca, Langston Patterson, and TJ Quinn, all looking to secure a spot on the roster. Mapu, who has prior NFL experience, was most recently waived by the Houston Texans after being acquired from the New England Patriots earlier this year. The Chiefs are actively seeking to bolster their linebacker depth in response to McDonald's injury.
