ASHBURN -- The Washington Redskins assembled for a brief practice Monday morning, less than 48 hours after the 53-man roster became official. That's official for now, as in written in pencil and not pen. Changes could occur before the Sept. 12 Week 1 matchup against Pittsburgh at FedEx Field. Injuries play a factor in such decisions. Getting a look at who was in and who was out of practice highlight Monday's notes.

  • Overshadowed with the 22 players released Saturday and the nine added to the practice squad Sunday was the official activation from the preseason Physically Unable to Perform list for one Josh Doctson. The rookie wide receiver participated Monday in full team practices for the first time since May. Doctson ran routes and showed no overt signs of favoring his sore left Achilles. "Today is the first day we saw him with pads, shoulder pads -- ever," coach Jay Gruden said over four months after Washington selected the receiver 22nd overall in the 2016 NFL Draft. It was good to see." Gruden was non-committal about whether Doctson would play in the opener. Smart money says no since he missed the entire summer, but we'll see after he practices more than one day.

  • The rookie spoke after practice and admitted he's "rusty." "I felt good . It's been three months," Doctson said. "It's always good to come out there and play football with my teammates. As for expectations, he said, "Just to get back a feel for the game." Doctson couldn't put a timeline on that feeling returning. "You'll just know one day, making plays in practice. ...I have to make plays out here before I can on Sunday or Monday."

  • Here's a quick look at No. 18 on the field. Now it's about shaking off the rust. On the second video, Doctson beat Greg Toler deep, but dropped the pass.

  • Matt Jones (sprained left shoulder) participated in unit drills, but wore a non-contact jersey. The second-year back, who didn't play in the final two preseason games,  told Breaking Burgundy last week he felt about "90 percent." On Monday Jones said the should feels "awesome" compared to even a week ago. If he's good to go, Washington probably stays with the three running backs on the roster. If concerns creep in, activating Mack Brown becomes a possibility. Gruden wasn't exactly ready to say Jones will face the Steelers, but it also seems like the non-contact jersey was precaution.

  • Pass rusher Ryan Kerrigan (groin) and offensive lineman Spencer Long (sprained right ankle) also participated in unit drills. However, defensive lineman Kendall Reyes worked on a side field. Neither Reyes nor Gruden addressed the matter after practice as teams are not forced to discuss injuries at this point in the work week. Stay tuned.
  • Two players not on the roster were on the field. Defensive tackle Louis Nix and former Jets tight end Wes Saxton are now on the practice squad, Gruden said. Nix, a former Notre Dame stalwart, was drafted in 2014 by Houston in the 3rd round. He spent last season with the New York Giants. Both of these guys in would mean somebody is out -- one open slot remained -- and fullback Joe Kerridge was not on the field Monday. The Redskins have yet to announce any moves.
  • Adjust your list of Redskins jersey numbers. We told you over the weekend that running back Robert Kelley went from 22, a number he shared over the summer with safety Deshazor Everett, to 32Ziggy Hood shifted from 73 to 90.

  • Speaking of Everett, his impressive work late this summer earned me a roster slot.
