Clubs like the Monsters and FC London are interested in the 21-year-old, with the current transfer window not closed until the end of March.
But the Ruckus are still in contention in the CSA Club Championship and CSA England Cup.
And Ruckus manager Harry Davies says Stretford is such a key player for his side, and hints that the 21-year-old could be picked for England World Cup side in the summer.
"We want to hang on to him as long as we can because he's such a key man for us," said Davies. "I hope Marco Garibaldi is listening - Stretty's is good enough to be in that World Cup side."
