The Cowboys placed Gallup (knee) on the active/PUP list Wednesday, Todd Archer of ESPN.com reports.
Gallup's status for Week 1 is still in question, so it's not much of a surprise to see him begin training camp on the PUP list, which means he's unable to practice. The 26-year-old wideout can come off the PUP list at any point in training camp if deemed healthy, though the Cowboys seem unlikely to rush him back on the field at less than 100 percent after having recently signed him to a five-year extension. Jalen Tolbert, James Washington (foot) and Noah Brown (hamstring) could handle added reps behind CeeDee Lamb as long as Gallup remains sidelined.
