Despite intercepting Philip Rivers three times on Thursday Night Football, the Oakland Raiders' secondary may have suffered a significant blow.

According to Ian Rapoport, star safety Karl Joseph was spotted using crutches last night, and is set to undergo an MRI on his foot.

The team will be anxiously awaiting the results of his MRI, which is scheduled for Friday, but Rapoport reports that the team fears the injury is serious based on the initial diagnosis.

Joseph suffered the injury on Thursday night after coming away with a game-sealing interception off Rivers. While the team was celebrating, Joseph could be spotted limping off to the sideline in pain.

Joseph is in his fourth NFL season, all with the Raiders. He's started 41 games of the 49 he's appeared in, logging four career interceptions, 15 pass defenses, 234 tackles and 3.0 sacks.

Joseph has been crucial to the team's success this season. He has started each of the first nine games and has helped anchor a defense that has allowed less than 22 points per game in its victories. He is also tied for second on the team with four tackles for loss.

The former first-round pick could be looking at a lengthy stint on the sideline, but we won't know the true severity of his foot ailment until after the results of his MRI.
