Running back Knowshon Moreno, who missed the first two and half weeks of training camp while on the physically unable to perform list, has passed his physical and is now active and ready to work.
Moreno, 27, immediately joins a running back competition that so far has been dominated by Lamar Miller, who has taken nearly 80 percent of the snaps with the first-team offense.
Moreno is expected to compete for the starting job but more likely will share the position and get much if not most of his time as the team's third down back -- a spot that takes advantage of his prowess as a blocker. Moreno is practicing today but he is highly unlikely to play Friday evening when the Dolphins open their preseason at Atlanta.
The timing of Moreno's return is good for the Dolphins because running back Daniel Thomas (hamstring) has been out the past two days, including today.
Other injuries the Dolphins continue to monitor include quarterbacks Matt Moore (shoulder) and Pat Devlin (hamstring) are not working much today. Devlin is totally out of practice and Moore is dressed out but not throwing.
Charles Clay (knee) is still out.
Olivier Vernon returned to practice today. Mike Wallace and Brian Hartline are practicing.
