Michael, who has been in training for his bare-knuckle fighting scenes as Ross Barton, admitted he suffered the injury when he tried to pick up a heavy weight.

“I popped my shoulder in the gym and it was because I saw a weight and thought I could pick it up – turns out I couldn’t lift it, and blew my shoulder out,” he said.
But Michael reveals he has enjoyed getting down and dirty for the fight scenes.
“It’s been really nice to film. It’s been really good fun. It’s been actiony and stuff and it’s made me get to the gym, I had to do a little bit of training… so I think I owe the writers for that,” he says.

The actor admitted it’s a change spending more time in the make-up chair.
“I spend more time in the make-up chair than I do on set sometimes,” he said.
“It takes about 45 minutes for the black eye and stuff because the cuts have got to be raised. So they have to put silicone, then cut into it and put the blood in. All very gross but good.”
