Cowboys' oft-injured Sean Lee dealing with knee injury

Dallas Cowboys linebacker Sean Lee is sidelined with a knee injury.

What It Means:

Head coach Jason Garrett claims the results were "positive" after Lee received an MRI on Monday, likely meaning they came back negative. This injury doesn't sound major, but it's a useful reminder of his checkered health record. The Cowboys defensive front seven is already missing members due to ailments and they can't really afford to add Lee to that list.
