Mark Wahlberg is nursing a bandaged hand after injuring himself while training for a new American football movie.

The actor has been spending time at an NFL training camp practising for his role as a footballer in INVINCIBLE - and he's been left battered and bruised.

And when quizzed about his strapped up hand and wrist on MTV show TRL today, the actor said, "I'm shooting a football movie, and some of the football players don't realise it's just a movie."
