Gallup sustained a strained right hip during Sunday's 41-33 win over the 49ers, Jon Machota of The Athletic reports.
Prior to his departure later in the game, Gallup had three receptions (on five targets) for 26 yards and one touchdown. While clarity regarding his status likely will arrive at some point in the coming days, the Cowboys still have Amari Cooper and CeeDee Lamb, backed up by Noah Brown, Cedrick Wilson and Malik Turner, at wide receiver if Gallup misses time.
