The Pittsburgh Steelers are actively working on a multi-year contract extension for Pro Bowl outside linebacker James Harrison, according to James Walker of ESPN.com Per Walker, the Steelers have been negotiating with the NFL Defensive Player of the Year’s agent, Bill Parise, as often as twice daily. Harrison recorded 16 sacks, seven forced fumbles and 101 tackles last season, also registering a dramatic 100-yard interception return for a touchdown in the Super Bowl, but was paid only a $1.2 million base salary. “It’s been a very open process, and it’s going about the way you would expect,” Parise said. “So I think everything is moving along. “Certainly the Steelers didn’t win six Super Bowls by not knowing what they’re doing. I’m sure they understand exactly what they have and where they’re going with James’ situation.” Harrison is signed through 2009, at a base salary of $1.4 million. Absent an extension either of his contract or the Collective Bargaining Agreement, he’ll be eligible for unrestricted free agency in the uncapped year of 2010.
