PITTSBURGH -- Pittsburgh Steelers safety Troy Polamalu has not been ruled out of Sunday's key game against the New York Giants despite sustaining the seventh concussion of his career last weekend.
Steelers coach Mike Tomlin confirmed Tuesday that Polamalu sustained a concussion while tackling Cincinnati Bengals running back Cedric Benson on Sunday, the same play on which cornerback Bryant McFadden broke his right forearm. McFadden is expected to be out at least a month.
Despite Polamalu's history of concussions, he may not miss any playing time.
"Tests are favorable at this point, he's slated to practice tomorrow [Wednesday] and we'll see how he goes," Tomlin said.
Pro Bowl running back Willie Parker, out for three weeks with a knee injury, may also return for the matchup of first-place teams with 5-1 records.
Tomlin says Parker will practice starting Wednesday. Parker has a sprained left knee and has not played since Pittsburgh's lone loss of the season in Philadelphia on Sept. 21.
Parker was on track to return Sunday against Cincinnati before aggravating the injury during practice early in the week.
Tomlin says if Parker doesn't have any setbacks this week, he will start Sunday.
The Steelers are hoping the same for Polamalu. His sometimes reckless tackling style in which he launches headfirst into a ball carrier has made him susceptible to concussions, although this is Polamalu's first in the NFL since he was hurt tackling the New Orleans Saints' Reggie Bush on Nov. 12, 2006.
