Harlequins have signed young Warrington forward Lee Mitchell on a month's loan.
Mitchell, 22, has made three substitute appearances this season - including an appearance against Quins last month.
Mitchell had been on dual registration terms with Leigh, who have now signed his Wolves team-mate Rhys Evans.
Bridgend-born Evans, 18, has played in seven of Warrington's 10 matches so far this year but lost his place to fellow Welshman Rhys Williams last weekend.
Mitchell, who has made 35 first team appearances, became a full member of the Warrington squad in 2008, making his mark with a try in a win over champions Leeds.
He takes his place in Quins' squad to face Catalans Dragons on Good Friday, in place of captain Rob Purdham, who went off injured during last Friday's 26-25 draw with Castleford.
Evans will go straight into the Leigh squad for their Championship fixture with Barrow, also on Friday.
Warrington, who expect to be able to select from a full-strength squad for the start of the Easter programme, are also allowing three members of their Under-20 team to join Championship sides on dual registration.
Brooke Broughton is going to Dewsbury, Mike Stewart to Rochdale and Chris Fleming to Whitehaven.
