Former Bedford academy graduate Corey Hircock has agreed to re-join the Blues from Munster.
The former Ireland Under-19s winger spent three years at the Blues before moving to Munster in 2010.
Hircock failed to break into the first team at Thomond Park, however he did win the British & Irish Cup with Munster 'A' last season and has been playing for Irish league side Garryowen.
Blues director of rugby Mike Rayer said: "We are really pleased that Corey is coming back home to the Blues.
"We wanted him to sign a development contract back in 2010 but when a club like Munster come knocking on your door you can't turn them down.
"Corey has developed well as a player during his time in Ireland and at just 22 years old he has a long future ahead of him and we are all looking forward to seeing him in a Blues jersey next season."
Meanwhile the Blues have confirmed Ben Cooper, Dan Seal, Paul Tupai and Tom Armes have all signed contract extensions.
