Houston has filed an appeal with the NCAA requesting a sixth year of eligibility for QB Case Keenum. Keenum, the school’s all-time leading passer, had his senior year cut short when he suffered a season-ending knee injury in the third week of the campaign. The previous season, Keenum amassed almost 6,000 yards of total offense and threw for 48 touchdowns. In order to qualify for the additional year, though, Houston will have to prove that Keenum redshirted his true freshman because of injury.
