Amari Cooper has been activated from the PUP list by the Cowboys -- after passing his most recent physical.

Walker went on to tweet the expectation isn't that Cooper will be fully unleashed in practice immediately, but instead ramped up to make sure he's full speed for Week 1 without risking a preseason setback. But he's good to go at the moment.

Cowboys WR Michael Gallup is enjoying his increased work in slot. “That’s a whole different route tree than playing outside. ...Everybody labels me as just a ‘deep-ball threat,’ but I know I can do a whole lot more.” Been focused on route-running, conceptual details this camp.

Gehlken went on to tweet that all three Cowboy WRs can play from the slot, which will add a new wrinkle to the offense. As Gallup said, corners won't be able to follow anyone and will have to change up the defense. Gallup could have some later-round fantasy value with his ranking of 49th and an ADP of the ninth round in 12-team leagues.

Cowboys WR Amari Cooper said he weighs 215 pounds now. Wants to play at 210. Faster.

Cooper said he has been 225 the past three seasons. Cooper’s goal is to have best season of his football career. Not just words, he said. Actions been intentional, the tweet all said. For fantasy purposes, he may be trying to hold off CeeDee Lamb, who is getting drafted ahead of Cooper in some leagues.

Cowboys WR Michael Gallup avoided serious injury in Sunday’s win over 49ers. Exited third quarter with a hip pointer, source said.

Gallup hasn’t been ruled out for Sunday’s divisional game against Eagles, the tweet said. And with the Cowboys and the rest of the NFC East teams still alive for the division, this will be a key game for both teams so Gallup may try to play through the injury. He produced a 3-26-1 line behind Lamb's 8-85-0 line last week, while Cooper had just two catches for 10 yards in the win over the 49ers.

The Cowboys plan to give Garrett Gilbert and Cooper Rush reps in practice and pick one of them at week’s end to start at QB against the Steelers.

The big news is it won’t be rookie DiNucci, who struggled Sunday night against the Eagles. As Pelissero added, the Cowboys are playing to experience at the position. We'll continue to monitor heading into Week 9, but it's probably safe to assume much of the same no matter who is named the starter, if not mostly because of the tough matchup against the Steelers. It continues to be a big downgrade for players like Elliott, Cooper and Gallup.

But Andy Dalton is not Dak Prescott, who was off to the best start of his career and the best start ever by a Cowboys quarterback.

The offense will have to change to a degree, relying even more on the run game.

Once Dalton entered Sunday, the Cowboys used more of Elliott, who had 19 carries for 91 yards, behind a remade offensive line that included two undrafted free agents at tackle (Brandon Knight and Terence Steele) and a rookie at center, the story said. The good news for potential Dalton owners is, he has never had the skill-player talent he has in Elliott, Gallup, Cooper and Lamb.

Cowboys head coach Mike McCarthy told reports Friday that WR Amari Cooper “went through the mock game and everything today. I don’t foresee a setback there.”

Cooper had his hands full Sunday night. The Cowboys are lined up for an offensive shootout with the Atlanta Falcons this Sunday, a game that Cooper would be expected to be a top 15 fantasy producer at wide receiver. His injury history is a concern and time sidelined will always be a concern with Cooper leading up to game day.
