Miami Dolphins tailback Knowshon Moreno has a logical explanation for sparingly working during the team's minicamp sessions this week, and not participating in Thursday's controlled scrimmage.
Moreno, who accounted for 1,586 total yards and 13 touchdowns as the Denver Broncos starter last season, has been battling a medical issue according to a source.
The source wouldn't go into specifics about the injury, but said Moreno has been hindered by it for a couple of weeks and needs time off to recovery.
This explains why Moreno hasn't been given many reps in practice. He has been running with the second or third string or not practicing at all in team drills. Lamar Miller currently sits atop the depth chart.
