Carl Pelini wants his job back at Florida Atlantic, asking school officials to rescind the resignation letter that he now claims he was forced to sign after being confronted with allegations that he used illegal drugs.Pelini, who was FAU’s head coach for 20 games, said he denied using the drugs, later identified in other documents as marijuana and cocaine. When FAU announced his resignation Oct. 30, athletic director Patrick Chun said Pelini and now-former defensive coordinator Pete Rekstis both acknowledged that they used drugs. “I denied using illegal drugs three times,” Pelini, who was 5-15 with the Owls, wrote in a letter Thursday to three FAU officials. Chun released a statement through an athletic department spokeswoman, saying he stands “by my statement and decision from last week.”“We had ample evidence to support the charges that we confronted both coaches with,” Chun said, declining further comment. Last week, two days after Pelini’s resignation was announced, the situation took a turn when school officials released sworn affidavits from two people, including FAU assistant coach Matt Edwards, alleging drug use. Briefly • North Carolina: Coach Roy Williams said leading scorer P.J. Hairston and senior Leslie McDonald won’t play in the Tar Heels’ season opener against Oakland tonight. They are out due to NCAA eligibility concerns, which have lingered over the program since a trouble-filled off-season. • TCU: Kicker Jaden Oberkrom, an Arlington Martin grad, received first-team Capital One Academic All-District honors, making him eligible for academic all-America consideration. Oberkrom is 12-of-16 on field goals and 25-of-25 on extra-point attempts. • Texas A&M: Kenneth Marshall, a freshman defensive back, was arrested on Tuesday on charges of possession of marijuana and prescription pills. Marshall, who redshirted in 2012, was suspended.
