Warrington threequarter James Saltonstall looks set to make his Super League debut for Bradford after his loan spell with the Bulls was extended into a second month.
The 19-year-old has played in all three of Bradford's pre-season games and impressed coach Francis Cummins, who said: "James is going to be staying with us for another four weeks or so.
"He adds further competition for places out wide and gives us some added depth going into the new season."
Forwards Joe Philbin and Tom Walker, who joined the Bulls at the same time as Saltonstall, have returned to Warrington and are expected to play for the Wolves' Under-19s this season.
Warrington coach Tony Smith said: "All three of them have been a credit to themselves and to our club. To be able to play a game or two for Bradford was a great experience for them and they have certainly come back better young men and better for the experience.
"At the moment we are happy for Saltonstall to stay at Bradford until we look at things further down the line and at what's the best spot for him either at Bradford or back with ourselves."
