The Kansas City Chiefs are calling Justin Houston's injury a hyper-extended knee, according to the KC Star's Terez Paylor.
Justin Houston has a hyperextended knee. He had a torn PCL before, but that has healed up. He's doing well and is day-to-day.

"We felt like we should clarify some things with Justin Houston, because there were some reports out there that he had a torn PCL," Chiefs trainer Rick Burkholder said, via quotes from the Chiefs. " What actually happened to him was he had a hyperextended knee. He had the torn PCL before - back in January of 2014 - that has healed up.
"With the hyperextended knee, you get some soft tissue damage in the back of your knee, and some of the ligaments and tendons and soft tissue get stretched out. That's what he's dealing with right now, he's in the middle of the rehab process. He's doing well and he'll be on a day-to-day basis as we go forward here."
BJ Kissel reports that Reid said there has been no decision made on Houston' status for Sunday, adding that he's made "big improvements" in the past two days. Which means it's possible he does return on Sunday. That would obviously be great news for the Chiefs as they try to strengthen their hold on the top Wild Card team in the AFC playoff picture. Houston keeps himself in great shape so, honestly, it's not that surprising to me that we're talking about this.
If he can't go, the Chiefs have Dee Ford back to practice after he injured his back. If Houston can't go, I would be really excited to see Ford given a full game. Although Ford rotates in when he's healthy, the Chiefs primarily use Houston and Tamba Hali. Frank Zombo and Dezman Moses are also options for the Chiefs.
