Castleford have lined up Warrington half-back Gareth O'Brien as a stop-gap replacement for the suspended Rangi Chase.
The Tigers have decided not to appeal the two-match ban imposed on Chase for a reckless tackle on Leeds full-back Zak Hardaker in last Sunday's 14-12 win over the champions.
Instead, they are to acquire the services of O'Brien, 21, who has been unable to force his way into the Wolves team so far this season and played on a dual-registration for Championship club Swinton last weekend.
Castleford announced on their website that O'Brien joined the squad for training yesterday and they expect to formalise a month-long loan deal with the Wolves today, in time for him to make his debut at Bradford on Saturday.
O'Brien, who had a month's loan with Widnes last season, has made 11 senior appearances for the Wolves.
