IRVING, Texas — Cowboys rookie running back Felix Jones is done for the season.

The team said today that Jones, one of Dallas' two first-round draft picks, will be placed on injured reserve because of a big left toe injury sustained while doing rehabilitation after hurting his left hamstring Oct. 12.

Jones returned to practice on a limited basis Wednesday, but the team now says that was to evaluate his ability to play with the toe injury. It is the first time the team confirmed Jones had a setback during rehab for the hamstring, which has healed.

Based on that practice and an evaluation by a foot and ankle specialist who reviewed an MRI of Jones' foot, the Cowboys decided Jones couldn't play again this season.

Jones rushed for 266 yards and three touchdowns in his six games. He also returned 16 kickoffs for a 27.1-yard average, including a 98-yard touchdown.
