Hobbs, a 5-11 sophomore from Johnson High in Huntsville, had been impressive in preseason practices after being plagued by a leg injury as a true freshman.
"She is out for the season," Auburn coach Nell Fortner says. "Not having Reneisha hurts our depth. She hasn't really been healthy since she has been at Auburn so we don't really know for sure what she was capable of doing on the floor.
"We had seen glimpses of what she could," Fortner says of the player who was Gator Player of the Year for the state of Alabama her senior season.
"She was really doing nicely at practice," Fortner says. "Losing her cuts into our depth. We are still fine in that department, but I was really wanting to see what she could bring to the table."
Hobbs is not the only player expected to contribute who is sidelined for the Tigers. Junior center Keke Carrier is academically ineligible for the first semester and it is not certain if she will rejoin the team in December.
