On August 17th, the Kansas City Chiefs’ Marcus Kemp injured his knee while making a contested catch during a preseason game vs. the Pittsburgh Steelers. Following the catch, he came up limping and was kept out of the rest of the game. An MRI the next day confirmed that he tore his ACL (anterior cruciate ligament) and his MCL (medial collateral ligament).

The MCL is a ligament that connects the femur (thighbone) to the tibia (shin bone). Its main job is to resist outward turning forces on the knee. MCL tears usually heal well naturally. Kemp will have ACL reconstruction with the goal of playing in the 2020 season.
