Dyer was a former two-time 1,000-yard rusher at Auburn and was named 2010 BCS national championship game MVP for the Tigers.
After spending time at Arkansas Baptist College, Dyer came to U of L with two years of eligibility left. But the first year he played limited time and was hampered by injuries.
Now, heading into his senior season there's renewed hope that he can return to close to the player he was while at Auburn.
"He just keeps getting better and better," U of L coach Bobby Petrino said about Dyer on Saturday during U of L's media day.
Dyer ran just 44 times for 223 yards and two touchdowns last season. He played in eight games but had his season cut short by an injury, which led to sports hernia surgery.
Petrino said it took him a little while to get back after the surgery but by the spring game Dyer looked healthy. He ran for 150 total yards - running for both teams - in the spring game.
"He is getting better," U of L running back coach Kolby Smith said, noting Dyer and the other backs just "need to keep taking a step forward" during the coming weeks.
Dyer was listed as the No. 3 running back on the depth chart heading into fall camp, behind Dominique Brown and L.J. Scott.
But Petrino said recently he "should have listed them as 1-A and 1-B. It's going to be a good competition between those guy."
