"Both of them are competing and we're doing some things with Gerald (Jones)," Fulmer said. "Both of them are really working. But we've been a good practice team; it's what we've done in the game that counts and we've got to make that carry over.
"We're certainly not going to give up on anybody, regardless of what happens."
Fulmer said he has been impressed these last two days with the defensive tempo that has carried over from last weekend's fine performance at Auburn. Tennessee limited the Tigers to just 226 yards of total offense in a 14-12 loss.
"I really like the way those young ends (Ben Martin and Chris Walker) are playing, I really like the way Gerald Williams is playing. Those guys are making some significant progress. And LaMarcus Thompson in the absence of Ellix (Wilson) - Ellix not being 100 percent this week; I do think he will be available for the game - has shown some progress. And Daryl Vereen moved to linebacker. He came back and looks like a very fast linebacker rather than a limited safety.
"Building that depth is really good."
Also returning to practice this week has been junior tight end Jeff Cottam (back), who Fulmer expects to see at least limited work in Saturday's game.
