Regarding Davis’ injury, Fowler’s source said simply, “it’s bad.” The Cowboys’ No. 2 running back is undergoing further testing, but we expect them to place him on injured reserve before long. The Cowboys waived RB Jaydon Blue and RB Phil Mafah last month. Blue has since signed with the Eagles’ practice squad. Currently, only RB Israel Abanikanda resides on the practice squad in Dallas.
