Sean Lee discovered that his neck injury is more serious than originally diagnosed.
Lee had an MRI on Thursday that displayed some ligament damage and he won't play for the Dallas Cowboys on Sunday against the Green Bay Packers.
"There’s no gray area," Lee said on The Fan. "I kind of have to let it heal for me to be able to even do my job. I wouldn’t probably be able to make it through the game until I let it heal. Hopefully it can heal up faster, and we’ll look at it next week."
