Seahawks wide receiver Darrell Jackson, who has been bothered by soreness to his right knee and lower back, returned to practice Friday to prepare for next week's Super Bowl. Jackson didn't practice last week, but caught six passes for 75 yards and a touchdown in Seattle's 34-14 victory over the Carolina Panthers last Sunday. He missed nine games this season after undergoing surgery on his right knee Oct. 12, returning to play in two of the Seahawks' final three regular-season games. He was inactive for the team's regular-season finale in Green Bay. He was hit in the back after catching a pass in Seattle's 20-10 playoff win over the Washington Redskins on Jan. 14.
