Lions lose key defensive veteran to a serious knee injury

Cominsky is expected to miss all of the regular season with the potential to return for the postseason

An unfortunate update on the health status of Lions defensive lineman John Cominsky. The veteran will miss significant time with a knee injury suffered during Tuesday’s practice at Detroit’s training camp.

Cominsky had his right leg rolled up on from the side at the end of a run play after he had assisted in the tackle. After initially trying to get up and walk it off, Cominsky angrily collapsed to the ground. He left the practice field on a cart. According to reports, including one from Sirius XM NFL Radio, Cominsky tore the MCL in his right knee.

The injury will require surgery that could keep Cominsky out for the entire season. Per Adam Schefter, Cominsky could potentially return for the postseason if the Lions advance into the playoffs.

Cominsky has been a regular contributor and part-time starter for the Lions defense for the last two seasons. In his first year in Detroit, Cominsky primarily played the EDGE spot and racked up four sacks in 14 games. The 2023 season saw the 280-pounder play more on the defensive interior, and his production fell off as a result. He was engaged in a camp battle with sixth-round rookie Mekhi Wingo, Josh Paschal and Levi Onwuzurike for playing time and depth chart status.
