IRVING, Texas -- Cowboys wide receiver Kevin Ogletree bumped knees with another player during Tuesday's practice and underwent an MRI exam.
Team officials don't think it's serious and it's uncertain if he'll practice on Wednesday. The Cowboys don't have to release an injury report on Tuesday but must do so Wednesday and Thursday.
Also, starting running back Felix Jones has a tight hamstring and he was held out of practice on Tuesday. It was mainly as a precaution. Jones is coming off a 22 carry 108 yard performance last week at Tampa Bay. Jones rushed for 100 yards in consecutive games for the first time in his career.
With Jones out, Sammy Morris got the bulk of the carries with the first-team offense. In his Cowboys' debut, Morris rushed 12 times on 53 yards after just three days of practice and being off for 12 weeks while he awaited for another team to sign him.
