Widnes have signed Wigan prop Greg Burke on a two-and-a-half-year deal.
The 23-year-old, who has been a regular for the Warriors this year after spending last season on loan at Hull KR, will link up with the Vikings immediately.
Widnes head coach Denis Betts said: "Greg is a really positive signing for us. He is a young British forward with lots of potential coming out of a great system at Wigan.
"He is ambitious and looking to develop himself whilst adding strength to our squad, increasing the competition for places here at the Vikings."
Burke is in line to make his Widnes debut at St Helens on Friday night.
"This is an exciting opportunity for me, to establish myself in a strong competitive Super League side week in, week out," he said.
"I already know a few of the boys, that makes the transition easier, and I can't wait to take the field with them and help cement the Vikings' place in the Super 8s this year."
