Also reported by Carey Murdock at Oklahoma's Rivals site Sooner Scoop, Oklahoma junior Trevor Knight has been granted a full release by the Sooners and has listed Kansas State as one school to which he's interested in transferring.
Under normal circumstances Knight would exhaust his eligibility by transferring within the conference, but the full release relieves Knight of the requirement to use an additional year in the process. As a result, if he did come to K-State he would be an eligible senior in 2016 as he's graduating in May.
Knight, of course, lost his job in Norman to Baker Mayfield, who was not granted the same courtesy by Texas Tech. Despite losing his spot on the depth chart, Knight has had numerous high points in his career, as well as some notable lows. Still, had he been wearing purple in 2015 he'd have been the best option available under center to Bill Snyder and his staff.
More as this develops.
(A previous version of this item incorrectly indicated Knight would have to sit out 2016.)
