Michigan's 14-9 victory over Penn State two weeks ago is under review.
There is a possibility the Wolverines may have to forfeit their Big Ten Conference win against the Nittany Lions because they used an ineligible player.
Artis Chambers, a freshman safety who enrolled at Michigan in January, appeared on special teams in each of the first four games. He had one tackle against Penn State Sept. 22 at Michigan Stadium.
Because it's a Big Ten eligibility issue, Michigan is only facing disciplinary action based on its conference opener against Penn State, according to the Ann Arbor News.
Big Ten spokesman Scott Chipman said today that a subcommittee is looking into the matter and could make a decision within two weeks. Chipman acknowledged that awarding a forfeit to Penn State is an option.
"We're referring all questions to the Big Ten," Penn State spokesman Jeff Nelson said. "We really don't have any additional comment at this point."
Chambers will not play for Michigan again this season, but he will remain on scholarship and continue to practice with the team.
