“It is with regret and deep humbling, that I am ending my playing career at the University of Houston," Sims said in a statement. "I have a lot of great memories that I will carry with me forever. I want to thank the University of Houston for allowing the opportunity to be a part of its football program. ...
"I don't know what my next step will be. I have one more year of eligibility, therefore I may look to play one more year of college football or I may enter the NFL Supplemental Draft later this year."
Sims says he'll make a decision on his next step in the near future. If he decides to transfer, Sims would be eligible in 2013 as he has already graduated from Houston.
Sims missed three games last season, but that didn't stop him from leading the team with 851 yards rushing and 11 touchdowns. He also caught 37 passes for 373 yards and another three touchdowns. In his career at Houston, Sims amassed 4,077 total yards and 37 total touchdowns.
