ALAMEDA -- Martez Wilson got his first work with the Raiders Thursday a day after being claimed on waivers from the New Orleans Saints.
Wilson, wearing No. 52, worked out with the linebackers but also could see time as a rush end in defensive coordinator Jason Tarver's system.
At 6-foot-4, 250 pounds, he looked bigger than the rest of the Raiders linebacking corps and he has five career sacks with only one start with New Orleans.
Expected to challenge for a starting role with the Saints, Wilson instead fell back on the depth chart and was active for four games under coordinator Rob Ryan.
Wilson was a third-round draft pick, No. 72 overall, 2011.
On special teams, Wilson tied for second on the Saints last season with 13 tackles and blocked a punt that was returned for a touchdown against the Washington Redskins.
Wilson's best play on defense came on a strip sack of Philip Rivers where he also recovered the fumble to preserve a win.
The Raiders injury situation remained unchanged, as center Stefen Wisniewski was participating in his second straight practice and looks on schedule to start against Pittsburgh.
Players who weren't practice and appear unlikely to be available include tackle Tony Pashos (hip), center-guard Andre Gurode (knee) and tackle Menelik Watson (calf). Safety Tyvon Branch (ankle) was not practicing and Jared Veldheer (rotator cuff) remains on injured reserve, designated for return.
