On the same day they clinched the No. 2 seed and a first-round bye, the Kansas City Chiefs may have lost one of their top defensive players for the postseason.
Rookie safety Juan Thornhill, who has been a major cog for an improving Kansas City defense in his first season, is feared to have suffered a "significant" knee injury. He was hurt in today's regular season finale against the Los Angeles Chargers.
The Chiefs will find out the diagnosis on Thornhill tomorrow.
A second-round pick out of Virginia, Thornhill started every game this season for the Chiefs, making 58 tackles and intercepting three passes.
He returned one of those interceptions for a 46-yard touchdown against the Oakland Raiders in Week 13.
Regardless of the extent of Thornhill's injury, Kansas City won't have to play next weekend. They earned a first-round bye thanks to today's win and the Patriots' shocking loss to the Miami Dolphins.
