Seattle Seahawks defensive lineman Jadeveon Clowney did not play during his team's win over the Philadelphia Eagles last Sunday due to what was initially deemed a knee and hip injury, but now, the Seahawks are giving Clowney's injury a different designation.

The club is now saying that Clowney has a core injury and he would not have practiced had Seattle held practice on Thursday (per Mike Florio of Pro Football Talk). He is expected to practice on a limited basis on Friday.

Also, according to Bob Condotta of The Seattle Times, Clowney told reporters that he sustained the injury during the Seahawks' Week 11 win over the San Francisco 49ers and said that his leg was “hard for me to lift up” at the end of the game.

In addition, Clowney stated that this is an injury he will need to manage for the rest of the season and said that he does not think he has to have surgery at this moment — an indication that he feels he may need to undergo a surgical procedure at some point (via Condotta).

He also did not say whether or not he would play against the Minnesota Vikings on Monday night (per Condotta), saying “we'll see how it goes.”

This has to be somewhat concerning for Seahawks fans, especially considering Philadelphia Eagles wide receiver DeSean Jackson made similar comments earlier in the season while dealing with his own core injury. He tried to return, but ended up making the injury even worse and ultimately underwent surgery to repair it.

Seattle acquired Clowney in a trade with the Houston Texans just before the season began.
