Danny Wilson will join Wasps ahead of the 2018-19 season.
It was confirmed in September that Wilson would not be renewing his contract at Cardiff Blues and would move on at the end of the current campaign.
He will now link up with fellow former Cardiff Blues boss Dai Young at the Ricoh Arena and while excited about the move he insists he remains fully committed to the cause at Cardiff Arms Park.
Wilson said: “I’m very excited about what the future holds however my commitment and full focus remains with Cardiff Blues for the remainder of my time here.
“I’m very grateful for the opportunity I have been afforded here and have enjoyed some great times. I’m determined to do all I can for the Blues until the end of the season and that begins with a massive home game against Sale Sharks on Sunday.”
Cardiff Blues take on Sale Sharks in a must-win European Challenge Cup clash on Sunday, December 17 (3.15pm). Tickets are still available and can be purchased here.
