Moten's career could be over unless he decides to petition the NCAA for a sixth season of eligibility.
"It's his third time in nine months," MacIntyre said. "So that's really, really, really sad. The kid has done a great job getting back. He's done a great job in school."
Moten, a product of Carson, Calif., who was recruited to CU by Dan Hawkins in 2009, led the team in special teams points in the 2012 season. He rose to the top of the depth chart at one point during spring ball in 2013, but tore his achilles in May and reinjured it in July last year leading to a redshirt season.
Missing all or most of two full seasons because of injury is a key component of most successful appeals for a sixth season of eligibility. But Moten also had a redshirt season in 2010 that might affect an appeal should he decide to pursue one.
