Castleford have agreed a one-month loan deal with Warrington winger Rhys Williams.
The Wales international has struggled for regular game time at the Wolves despite scoring three tries in the five appearances this season.
However he will now team up with the Tigers in time to his debut against Wakefield on Saturday - just a week after he faced the Wildcats for the Wolves.
Castleford head coach Ian Millward told the club's official site: "He's always been a player of outstanding natural ability and he played very strong against Wakefield at the weekend.
"He comes with speed and also a great desire to get his hands on the ball.
"I brought him in because we are short on outside backs and we haven't been consistent in that area. It is not often at this stage in the season that you can pick up a talent like Rhys and I'm looking forward to his involvement in the coming month."
