Mildenhall Fen Tigers have completed their 2011 line-up with the addition of Aaron Baseby in reserve.
The 20-year-old former Somerset Rebels rider will share the berth with Australian youngster Cameron Heeps.
Although Heeps, 15, is still waiting on the completion of paperwork so will be covered by Danny Stoneman, who has had spells at Weymouth and Bournemouth.
"We'll be sitting down and working out the final pairings later in the week," said team manager Rob Henry.
"I'm sure Aaron will be a great asset and that young Danny will do a good job for us until Cameron arrives, and who knows beyond that."
Mildenhall get their National League campaign underway when they host the Dudley Heathens on Sunday.
