Once at the hospital, doctors examined Smith and it was determined that he would need emergency surgery for an appendicitis attack.
The doctors performed an emergency laparoscopic procedure on the Tigers' tailback to fix the problem and he is doing fine at this time, Auburn's head football coach told Inside the Auburn Tigers.
Tre Smith was redshirted last season while Carnell Williams and Ronnie Brown were the featured backs.
Due to the fact that it was the more minor procedure, Tigers' head coach Tommy Tuberville said Smith would likely recover more quickly than if the appendix had ruptured.
"If they cut on you it's a month and a half that you'll be out," Tuberville said on Tuesday night. "Evidently, if it is not ruptured they can just scope it and he won't be out nearly as long. The doctors said he will be out a couple of weeks."
However, Tuberville said he would not speculate on an actual timetable for Smith's return to action, but added that he hoped he could be back in action in time for the season opener versus Georgia Tech on September 3rd.
Tailback Kenny Irons is ready to play after redshirting last season.
Smith finished spring drills first team on the depth chart. Two other tailbacks had solid springs for the Tigers--South Carolina transfer Kenny Irons, a junior, and redshirt sophomore Carl Stewart.
Redshirt freshman Brad Lester is the only other scholarship tailback on the team. He missed spring drills due to injuries, but is ready to play when practices start in August.
