Plymouth have confirmed a change to their plans for the forthcoming meeting with Scunthorpe, with Tate Zischke coming in as a guest for Ben Barker.
The club has also said it has not been possible to source a guest for Danny King, meaning the Gladiators will run rider replacement against the Scorpions.
It is the latest adjustment for Plymouth as they continue to manage team availability ahead of another Cab Direct Championship meeting.
