Redskins director of sports medicine said moments ago that left tackle Chris Samuels sustained a sprained medial collateral ligament in his right knee and was scheduled for an MRI to determine the severity of the injury.

Samuels went down late in the Redskins' practice this afternoon while engaged with a pass rusher.

On his way out of Redskin Park tonight, Samuels said: "Two guys fell into my leg. ... I think I'm OK. I didn't feel anything pop."

In February, Samuels, 30, had surgery on his left knee. In 2003, he missed three games with a right knee MCL injury.
