Dallas Cowboys running back Jaydon Blue was unable to participate 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 team's preseason opener last weekend, Blue had 10 touches and gained 34 yards while competing for the backup running back position behind Javonte Williams. His absence raises concerns about his availability for the upcoming game against the Arizona Cardinals. If Blue cannot play, Malik Davis might have the chance to take on the RB2 role.
Further information about the severity of Blue's injury has not yet been disclosed.
