James Harrison hasn't given up on returning to the Steelers, but Pittsburgh is officially moving on.

Ed Bouchette of the Pittsburgh Post-Gazette reported Tuesday that the team informed Harrison they have no interest in bringing him back for the 2013 season, according to a source.

The Steelers are thin at outside linebacker, but reworking a deal with Harrison -- who was released earlier this month -- hasn't been a priority.

Pittsburgh recently hosted former Dallas Cowboys linebacker Victor Butler and there was genuine interest in Elvis Dumervil, according to Bouchette. Dumervil's decision to join the Ravens wiped out Harrison's hopes of landing in Baltimore, and the market for the 34-year-old pass rusher has been quiet.

Pittsburgh is making the move to get younger on defense and parting ways with Harrison has a lot to do with the team's plans for Jason Worilds. The 2009 second-round pick was lodged behind Harrison and LaMarr Woodley in the lineup last season, but coach Mike Tomlin hinted last week that Worilds represents a changing of the guard.
