Todd Rice has resigned as the Pitt football team's strength and conditioning coach, a school official confirmed in an email Friday.
Rice was hired by Pitt coach Paul Chryst when Chryst took the head coaching job in 2012, and spent the last two seasons as the team's head strength and conditioning coach.
The school did not provide a reason for Rice's resignation. Pitt will hire a full-time replacement some time after Jan. 1.
Pitt has had problems with back injuries, especially along the offensive line, this season. Both left guard Cory King and left tackle Adam Bisnowaty have missed multiple games with back issues.
Chryst said earlier this year that the spate of injuries was something he would look into during the offseason, and make adjustments if necessary.
"You are concerned about [injuries]," Chryst said. "You don't know what drove those. Did it just happen? Is it something we are doing? You go through all of that and try to answer it.
