As far as Covey is concerned, yes. If he played so much as one snap in any postseason game, he’ll have forfeited his redshirt.
That said, I do seem to recall there being a clause for students who are sitting out due to transfer eligibility issues to be made eligible for the postseason if they’d signed their current school’s LOI past their 12th calendar month. So if Cam Rising were to have signed his LOI on Dec. 31, 2018, he’d be eligible to play for Utah on (or after) Jan. 1, 2019.
So does anybody know when Rising signed his Utah LOI?
