Belle Vue Aces plan to give 17-year-olds Kyle Howarth and Jason Garrity an Elite League ride because of injuries.
New Polish signing Borys Mitsurki, who has yet to make his debut, has suffered an injury and must be replaced.
"We were left with the question of replacing Mitsurki as we don't know how long he will be absent," said team manager Jim Lynch.
"We would like to give them both an opportunity so we'll use Howarth on Wednesday and Garrity on Friday."
The pair are both from Manchester and have been riding for the club's junior team Belle Vue Colts.
