Beason injury causing concern for Panthers

Posted by ESPN.com's Pat Yasinskas

There's a lot of uncertainty right now about the knee injury Carolina middle linebacker Jon Beason suffered in Saturday night's preseason game in Miami.

ESPN's Chris Mortensen was at the game and here's what he had to say on his Twitter account:

Just left Dolphins-Panthers. Bad new(s) for Panthers: Pro Bowl MLB Jon Beeson on crutches with "at least" MCL injury...stay tuned on this one.

Coach John Fox gave the same very-guarded answer he gives on just about every injury.

"I'm not a doctor, so the doctors will look at that and we'll know more after he gets evaluated,'' Fox said.

Beason told reporters he'll have an MRI on Sunday, but sounded optimistic. Still, this one has the potential to be scary if Beason has to miss any time. People are just starting to realize Beason is one of the best linebackers in the league. The Panthers have a quality backup in Dan Connor. But Beason is the leader of the defense and a true playmaker.

As Mort said, stay tuned on this one.
