"Well, he still has to go through the routine, the process," Coughlin said Wednesday. "(But) we're hopeful, confident that he will pass."
Rolle suffered the injury late in the Giants' 29-24 win Sunday over the Dallas Cowboys. Appearing on WFAN radio on Tuesday, Rolle also expressed confidence that he will play against the Steelers.
"So far, the tests that I've gone through have been pretty good. I just have a few more tests to go through come Wednesday," Rolle said. "But if it's up to me, I'm definitely gonna be out there come Sunday. I feel fine. I feel very good as of today."
Rolle did not practice Wednesday. But fellow safety Kenny Phillips, who has missed the team's past four games with a knee injury, practiced fully.
Stevie Brown, Phillips' replacement, was named the NFC Defensive Player of the Week after recording two interceptions and a fumble recovery against the Cowboys.
"Stevie Brown has had an outstanding run here," Coughlin said. "My position has always been, the more outstanding football players, the better. We'll find ways to involve all of them."
Several other Giants did not practice Wednesday: Center David Baas (ankle/elbow), linebacker Chase Blackburn (hamstring), running back Ahmad Bradshaw (foot), tight end Bear Pascoe (ankle), linebacker Keith Rivers (calf) and linebacker Jacquian Williams (knee).
