Castleford have explained their decision to let Brent Sherwin leave and have signed a short-term scrum-half replacement.
Kyle Wood has joined the Tigers, initially on a month's loan from Huddersfield, and he could go straight into the side to play Hull on Sunday. Sherwin could make his debut for the Catalan Dragons against Salford tomorrow, having agreed a deal for the rest of the season.
The Catalans have been seeking a play-making half-back since the unscheduled departure of Adam Mogg for Australia earlier this season, but failed in a bid to sign Melbourne's Brett Finch. Now they hope that the 32-year-old, injury-prone Sherwin will give them the direction they have lacked.
"He wasn't in our plans, so the timing was right and this move will give him the chance to stake a claim for a longer contract with the Dragons," said Castleford's chief executive, Richard Wright.
Wakefield have brought their front row up to strength with the signing of Charlie Leaeno from the Australian NSW Cup club Newtown. Leaeno, originally from American Samoa, has NRL experience with St George Illawarra and Canterbury.
"Charlie will give our pack more punch and me more options," said the Wildcats' coach, John Kear, who has signed him as a direct replacement for Shane Tronc, who went home to Australia last month because of homesickness.
Salford have offered their Australian half-back Daniel Holdsworth a new three-year contract, but face competition from at least three other Super League clubs.
Wigan's Test centre Martin Gleeson has been recalled to their squad for their game at Crusaders tomorrow, after being dropped last weekend for breaking the club ban on midweek drinking.
The Leeds full-back Brent Webb has failed in his appeal against a two-match suspension for a reckless high tackle.
