Wolverhampton Wanderers have confirmed that they have signed Joe Mason from Cardiff City for an undisclosed fee.
Mason joins Wolves on a three-and-a-half-year deal, becoming the club's second January arrival following Will Randall's switch from Swindon Town.
"We are delighted to be bringing Joe to the club. We've looked at him for a while, and particularly back in August, but the deal couldn't get done," Wolves manager Kenny Jackett said in a statement.
"He had a good loan spell at Bolton and he's a natural number 10, plays best just off a striker I think. Getting the right partnership in that area is a key one for us. And since [Benik] Afobe and [Nouha] Dicko have gone out of it for different reasons it's something we're looking to obviously try to improve.
"I think he would be one part of that, and he is a very good addition. I like his work rate, I like his football, and I think he's a natural to play behind the striker in my ideal 4-2-3-1 formation."
Mason joined Cardiff in 2011 and scored against Liverpool in the 2012 League Cup final at Wembley.
