Mildenhall Fen Tigers captain James Brundle has been handed a doubling-up position with Premier League Rye House.
The 24-year-old, who has second-flight experience with King's Lynn, will join the Hertfordshire club on loan.
He has averaged over nine points a meeting in his seven National League outings this term.
"We've agreed he can join the Rockets on loan, but Tigers matches will still come first," said Mildenhall co-promoter Michael Lee.
"It's a great opportunity for James to re-establish himself at a higher level, which is something all the boys in the team should be aspiring to.
"We should benefit as well, as the extra rides James will get in the Premier League will make him even sharper than he already has been when he rides for us in the National League."
