Bobby Petrino won't appeal termination

Former Arkansas head coach Bobby Petrino won't appeal the decision to terminate his contract with cause, a source close to the coach told ESPN's Joe Schad Friday.

Petrino was let go Tuesday for violating a morals clause after failing to disclose his inappropriate relationship with Jessica Dorrell, whom Petrino hired as a recruiting coordinator for Arkansas' football team, and withholding other information from athletic director Jeff Long.

Petrino's contract called for an $18 million buyout if he were fired without cause, but Long determined that Petrino's actions meant that he could be fired with cause. Petrino's contract stated that Long had the right to suspend or fire the coach for conduct that "negatively or adversely affects the reputation of the (university's) athletics programs in any way."

The source told Schad that Petrino had accepted responsibility for his actions and his firing.

The Associated Press also obtained the content of Petrino's text messages that were still available on his business phone through a Freedom of Information Act request.

In some, Petrino asked assistant athletic director Chris Wyrick about his job status the day after he was put on paid leave. Petrino also apologized to Long and asked someone if an investigation would uncover his text message content.
