DeMarco Murray has insisted that he can keep himself fit enough to play a full season in the NFL.

The running back has been missing from organised team activities with the Dallas Cowboys this week, having sustained a hamstring injury.

The 25-year-old told the Fort Worth Star-Telegram: "That's something I can't control. I can't control if anything happens. All I can do is go out there, play hard, play fast, play physical. Once I'm out there, I don't think there's any question about anything.

"I am going to play all 16 [regular season games] this year, and I'm excited. It's going to be a great year for us."

Murray has missed nine games through injury since being drafted by the Cowboys in 2011.
