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 Cowboys' preseason opener last weekend, Blue had 10 touches and gained 34 yards. He is vying for the second-string running back spot, competing with Javonte Williams. If Blue cannot play in the next game against the Arizona Cardinals, Malik Davis could take advantage of the situation to claim the RB2 position. No further information about the extent of Blue's injury has been released.
