Mark Wahlberg has revealed that he injured some of his friends during his training for new movie The Fighter.
The actor is back on the big screen next month in the boxing film that sees Wahlberg take on the role of 'Irish' Micky Ward.
The actor underwent an intense training programme for the film and admits to taking on some of his friends.
Speaking to The Independent the actor said: "I feel bad saying it but I've fractured a lot of ribs on other people and a lot of concussions.
"One friend had some bleeding in the brain and that wasn't good and it happened at my house. We're still friends and he came back to train. We never punched in the head again but we'd still spar to the body.
"Another guy cracked his rib on this side and then he tore the muscles on the other side in pain and he kind of collapsed holding both sides and his pants fell down to his ankles.
"We felt bad that he was hurt but it was so funny that his pants fell down. But those are the risks you take going into the ring. Everybody who goes in is aware of that."
Wahlberg is currently filming Contraband with Ben Foster and Kate Beckinsale.
The Fighter is released 4th February.
