Oakland Raiders safety Charles Woodson dislocated his shoulder against the Cincinnati Bengals, his agent, Carl Poston, told ESPN's Josina Anderson.

Woodson was slated to undergo an MRI Monday to reveal the severity of the injury.

The team didn't reveal the extent of Woodson's ailment after Sunday's game, after the veteran safety walked off the field in obvious discomfort late in the fourth quarter.

Woodson is one of the longest-tenured players in the NFL, winning Defensive Player of the Year honors in 2009. The eight-time Pro Bowler is integral to the Raiders' defense, and it would be a harrowing loss for the club if he's out for a prolonged period.

The 38-year-old won the Heisman Trophy in 1997 - the only defensive player ever to do so.
