Miami Dolphins' Knowshon Moreno unsure on injury return

Miami Dolphins running back Knowshon Moreno has admitted that he is unsure when he will be able to get back on the practice field in training camp.

The 27-year-old underwent knee surgery in June after a difficult start to his side's off-season activities, following his arrival from the Denver Broncos.

With the season just a month away, the back has admitted that he does not know when he will return to action.

Moreno told the Miami Herald: "I don't know. I don't know. I really don't even know. I just want to take each day one at a time. "They have a schedule for me and they're just going to tell me every day what I have to do, and I just go out there and do it."

Moreno ran for 1,039 yards along with 10 touchdowns for the Broncos last season.
