"He's going really well," Ward told the Telegraph. "He's got it together and he's pretty keen on playing again.
"He wants to do it for himself as much as anything. But even if he doesn't play, he's fit and healthy and stable, which is the main thing."
He added: "I remember his first day at training, we were running and he couldn't do it - he was walking.
"He was probably 120kg when he started and now he's probably about 100kg.
"He was massive when he came in but he's been training his arse off and he's still got it. Now he's running around no problems and he's really flying."
