McCoy would be making his NFL regular-season debut against the Steelers. Mangini said the possibility of McCoy playing will depend on the status of quarterbacks Jake Delhomme and Seneca Wallace, who are both battling ankle injuries. Neither will practice on Wednesday.
Mangini said he has confidence in McCoy, a third-round pick who struggled throughout much of the exhibition season. McCoy will get the majority of the snaps with the first-team offense in practice, Mangini said.
