Steelers activate James Harrison off PUP

The good news keeps in pouring in for the Steelers. On the same day that wide receiver Mike Wallace signed his restricted free-agent tender, the Steelers also received a boost on defense, where they activated linebacker James Harrison off the Physically Unable to Perform (PUP) list.

This isn't a major surprise because no one expected the Steelers to keep Harrison on PUP to start the season, which would have forced him to sit out the first six weeks of the regular season. But it's an encouraging sign that Harrison is ready to get involved in on-field activities.

Harrison, the 2008 Defensive Player of the Year, is targeting to play in the Sept. 9 regular-season opener after having his knee scoped on Aug. 15. Some believe it's very questionable whether the 34-year-old Harrison will be able to play against Peyton Manning and the Broncos. But, as coach Mike Tomlin has pointed out, Harrison has been a quick healer. Before missing four games last season, he had been sidelined one week in his previous four seasons.

In addition to Harrison, the Steelers also removed Jason Worilds (wrist), Harrison's backup, off the PUP. Pittsburgh has been going with third-string Chris Carter at outside linebacker.
