Joiner informed Scout this week that he has transferred from the program and will play for Navarro Junior College in Corsicana this season.
The lineman has actually moved over to the opposite side of the ball and will line up at defensive end this year. Joiner still has four years to play four and will be eligible to transfer immediately after the season.
"I really want to pursue playing in the Big 12, Pac-12, or SEC," he said.
Joiner started 21 games on the offensive line at Temple High School, including 11 games his senior year at left tackle and helping lead the Wildcats to a district championship. He was a unanimous District 8-5A first team selection.
Joiner joins a storied program at Navarro under first year head coach Cody Crill, who enters his fourth year with the program after spending three seasons as the Bulldogs' offensive line coach. Navarro had six players sign with Division-I programs last season including Texas, Baylor, and Texas Tech.
