Sources at Redskins park say that his leg was rolled up on during practice.
Early reports from team personnel are that it is a sprained knee. They also report it is a MILD sprain.
Official word will come later when the doctors get to Redskins Park and examine him.
7:00 P.M. Update:
Chris Samuels sprained the MCL in his right knee and has been taken to get an MRI. The Redskins should have an update around 8 p.m. as to the severity.
From the man himself:
"I'm OK. I didn't feel anything pop. It's just a sprain ... I thought it was over with for the season [when it happened], but the Good Lord blessed me. I know that I'm fine."
