Joyner, who has gone back and forth between defensive end and linebacker at Miami, leaves as UM landed the grad transfer of Tennessee pass rusher Deandre Johnson on Saturday night.
The Hurricanes lose Joyner as they are also set to lose their two starting defensive ends from the past season, Jaelan Phillips and Quincy Roche, to the NFL draft.
Last week’s Cheez-It Bowl loss to Oklahoma State served as a preview of what Miami returns at the position. Redshirt freshmen Jahfari Harvey, who had a strip-sack, and Cameron Williams, who had a tackle for loss, started.
