Pittsburgh Steelers linebacker James Harrison said he is scheduled to undergo surgery on his right shoulder Monday.
"Should only be down 4 to 6 weeks," Harrison tweeted Friday.
Harrison injured the shoulder during the Steelers' AFC divisional-playoff victory over the Baltimore Ravens, but he played in Super Bowl XLV, recording one tackle and one sack in the 31-25 loss to the Green Bay Packers.
The four-time Pro Bowl linebacker was unhappy with his performance in the title game.
"I don't feel anything but pain," he said after the game.
Harrison comes off another impressive season in which he had 10.5 sacks. He's a problem for receivers and tight ends coming across the middle, and for offensive linemen trying to protect their quarterbacks. Harrison was fined $100,000 by the NFL for illegal hits this season.
Harrison was named the NFL Defensive Player of the Year after the 2008 season, and he capped that campaign with a 100-yard interception return for a touchdown in Super Bowl XLIII.
