Dallas Cowboys running back Jaydon Blue did not take part in a joint practice with the New Orleans Saints due to a shoulder injury, as reported by Patrik Walker from the Cowboys' official site.
In the Cowboys' preseason opener last weekend, Blue had 10 touches and gained 34 yards. He is competing for the backup running back position behind Javonte Williams and is anticipated to receive considerable playing time this preseason. If Blue cannot participate in the upcoming game against the Arizona Cardinals due to his shoulder issue, Malik Davis may have a chance to claim the RB2 role.
Further information regarding the extent of Blue's injury has not yet been disclosed.
