PITTSBURGH -- Well, that didn't take long.
The signing of Keisel led to several changes on a depth chart that coach Mike Tomlin said he pays scant attention to during the preseason.
Keisel is back at the position where he has started since 2006 with Stephon Tuitt, Nick Williams and Ethan Hemer listed behind him. Cameron Heyward is the starter at left defensive end with Cam Thomas, Brian Arnfelt and Josh Mauro listed behind him.
Prior to the re-signing of Keisel, Heyward had been the starter at right defensive end with Thomas the starter at left defensive end and Tuitt behind Thomas.
Keisel made the trip with the Steelers Wednesday afternoon to Philadelphia, but he is not expected to suit up for the Steelers' 7:30 p.m. ET game against the Eagles Thursday night.
What is clear is the Steelers did not bring back "Da Beard" to play a limited number of snaps and mentor their young defensive linemen.
Heyward has been practicing at right defensive end but he should be fine moving back to the position where he emerged as a starter last season. The fourth-year veteran has said there is not much difference in playing right and left defensive end.
Thomas appears to lose the most with Keisel back.
He is now relegated to the Al Woods role of swing defensive end/nose tackle. Thomas, however, also provides injury insurance at nose tackle and could push Steve McLendon there if the latter struggles this season.
