Kansas City Chiefs defensive end Tyson Jackson left Monday's game against the San Diego Chargers with some sort of leg injury. Chiefs trainers came out and worked on Jackson while Todd Haley watched. Jackson later walked off with the help of the trainers and did not return.
I saw him in the locker room after the game but didn't get a good look at any noticeable injury.
Nick Wright of 610 Sports reports that a MRI confirmed today that Jackson has a sprained MCL. Per Wright, he's expected to miss 1-2 weeks. The Chiefs don't comment on injuries so the only confirmation we'll likely get from this will come from the injury and practice reports.
If that injury sounds familiar, that's because it should. It's same injury that Matt Cassel reportedly suffered in the third preseason game of the 2009 season. He ended up missing the final preseason game and the first regular season game.
When Jackson left the game, it was Shaun Smith that replaced him.
Haley said after the game when asked about defensive Glenn Dorsey that "we are thin there" but I'm going to disagree with him and say that defensive end is one of the few positions the Chiefs can afford an injury. Sure, no injury is easy to handle but the Chiefs can make it through this one, if the report is accurate.
