But on Wednesday morning, Moreno, who is listed as the Miami Dolphin's fourth-string running back but is expected to battle incumbent Lamar Miller for the starting job, was all smiles after participating in his first practice since undergoing arthroscopic right knee surgery in late June.
“It feels good to put the pads on and work with the guys,’’ said Moreno, who recently turned 27. “I’ve been getting a lot of mental reps. Now I’ve just got to put these things together.
“Today was testing it out and seeing how it feels. I feel good what I did today ... Now the next couple of days I’ll just progress and do more and more each day.’’
Moreno was taken off the Physically Unable to Perform list and placed on the active roster. It’s unlikely that Moreno, who was very limited in practice, will play in the preseason opener Friday night against the Atlanta Falcons, leaving the rushing chores to Mike Gillislee, Damien Williams and Orleans Darkwa.
“This was his first practice out here today, so I don’t know if it would be a wise coaching decision [with] a guy like that [who] really hasn’t participated to throw him in a game yet, but I’m not revealing any inside secrets,’’ Dolphins coach Joe Philbin said.
Moreno said he is not worried about where he appears on the team's depth chart.
"I can't really think about the depth chart and things like that," he said. "Wherever the coaches want to me to be, that's where I'll be. I just want to come out here and work."
The 5-foot-11, 218-pound Moreno has clearly slimmed down since sitting out minicamp in the spring. He’s coming off a career-best season for the Super Bowl finalist Broncos as he gained 1,038 yards on 4.3 yards-per carry with 60 catches for 548 yards. His 1,586 yards from scrimmage ranked fifth in the NFL, and his 13 touchdowns, 10 rushing, tied him for fifth most.
