Oldham have signed former St Helens halfback Lewis Charnock on a two-year deal from Barrow.
The 25-year-old made six appearances for Saints between 2013 and 2016, whilst also having loan spells with Rochdale, Leigh and Bradford.
He signed for Barrow permanently in 2017 and went on to make 53 appearances for the Raiders, scoring 18 tries and 124 goals.
He will now link up with Roughyeds boss Matt Diskin once again, who was assistant coach when Charnock was at the Bulls.
“When he (Diskin) told me there was an opportunity at Oldham I jumped at the chance of working with him again,” Charnock told the Oldham website. “It’s tough in the Championship, especially when you’re up against full-time opponents. Hopefully, I’ll be injury free and able to play my best rugby.
“I’m certainly looking forward to it — and looking forward to working with Matt again.”
Oldham head coach Diskin added: “I’ve tried to sign Lewis in each of the three years I’ve been a coach in the Championship. He plays it close to the line and for a half-back he’s very tough and very brave.
“He’ll be a massive addition to our half-backs.
“He’s had a couple of what I call freak injuries because he’s such a combative player, but he’s fully fit and ready to go and I’m delighted to get him. He has the qualities we’ll need to be competitive in the Championship.”
