Two injuries in the past two days have shaken up Kansas football's running back depth chart.

At Sunday's scrimmage, senior Brandon Bourbon tore his anterior cruciate ligament (ACL) and will be out for the 2014 season. On Monday, in a non-contact injury, senior Taylor Cox tore his Achilles tendon, also ending his season.

Both Bourbon and Cox have decided to stay at Kansas to further their education as both student-athletes have already earned their undergraduate degrees. They will have surgery and go through rehab in Lawrence, while Kansas explores the opportunity to file for a sixth-year clock extension due to injury.

"I feel bad for both Brandon and Taylor as they were looking forward to the opportunity to be the replacement for James Sims," said Kansas head coach Charlie Weis. "I sat down with each of them individually and talked through their options and was happy that they chose to further their education, while attempting to play again next year if things work out."

These injuries have opened the door for newcomers junior De'Andre Mann and freshman Corey Avery. To improve the quality of depth at running back, freshman Joe Dineen, Jr., has moved from safety to running back.

"I surveyed our roster and felt Joe was the best answer to help offensive depth, while not greatly hindering the defense," said Weis. "He and I met after practice Monday and I gave him the choice. He was happy to move in the best interest of the team.

"While De'Andre and Corey lack experience on the Division I level, they both have had excellent camps," added Weis. "The team is well-aware of this situation and is excited to make the run game successful."
