Coach Tommy Tuberville says he is making the move because offense should be a good fit for Green and with the Tigers losing two reserve offensive linemen more depth is needed on offense.
The Tigers lost talented redshirt sophomore Jarrod Britt, who retired from football after doctors said he needed to make the move so a chronic shoulder injury can heal.
Another guard, third team redshirt freshman William Sullivan, is expected to transfer to another college closer to home after finishing summer classes at AU. He is looking at East Carolina, Western Carolina and others.
"Tyronne is a good, big athlete and he has the type of lateral quickness that we need for an offensive lineman," Tuberville says. "He is already big and probably is going to get even bigger and if he does he might not have the quickness we are looking for on the defensive front.
"We have had some success moving other defensive linemen to offense," Tuberville adds. "We think this one can work out well, too."
Green, a 6-3, 310-pounder from Woodham High in Pensacola, Fla., redshirted last fall. He missed part of the 2004 practices with injuries, but made progress in winter workouts and spring training. He was a backup at both noseguard and defensive tackle on the depth chart, but wasn't on the three-deep at either position.
Nall says he is looking forward to working with Green. "We believe he is a good athlete who will be able to help us on offense," the line coach says. "I talked to him about it and he seems excited about the opportunity on offense."
Two of Auburn's projected starters on the offensive line, returning starter Ben Grubbs, a junior, and Tim Duckworth, who is also a junior, played defense prior to moving to offense.
