Here is the release from the University of Oklahoma Web site Soonersports.com on DeMarco Murray's surgery:
Oklahoma running back DeMarco Murray will undergo surgery on Dec. 22, and will not play in the 2008 BCS National Championship Game. The sophomore has a partial rupture of a hamstring tendon in his left leg.
"Obviously we're very disappointed for DeMarco," said OU Head Coach Bob Stoops. "He has been an important part of our success this year and we will miss his contributions. DeMarco has had an incredible year.
"With Chris Brown and Mossis Madu, we still have two very fine backs. Our team has a lot of confidence in their abilities."
Murray sustained the injury on the opening kickoff of the Big 12 Championship Game against Missouri on Dec. 6. Initially, it was thought that Murray had sustained a bruise, but an MRI performed on Dec. 8, revealed the additional damage. After weighing options, it has since been determined that surgery would be performed.
According to OU Head Athletics Trainer Scott Anderson, it will be approximately five months before Murray is cleared to resume training.
