Pettrey's father, Steve, said that he is hopeful that his son will be back in time for the team's bowl game.

"(Aaron) was really disappointed when he called me Saturday after it happened," Steve Pettrey said.  "He knew it was something pretty bad.  He's coming around though.  He wants to get it over with, start the rehab and hopefully be back by the bowl game."

The kicking duties will either fall on Ben Buchanan or Devin Barclay, although it looks like field goals and extra points will be handled by Barclay, Tiberi reported.

Barclay, who played for the Columbus Crew in 2004-05, successfully kicked one of three field goal attempts on Saturday.  He made all three of his of his extra point attempts.

Buchanan has not attempted a kick this season.
