Harry Mills and Charlie Tasker have signed their first professional contracts with the club.
Both are 18-year-old defenders who joined the club in 2014.
The pair have made the step up from the under-18s to the under-21s this season.
Under-21s head coach Shannon Ruth said, “We’re pleased that two players who have been with the academy for a long time will be continuing with us.
“Both have had excellent educations in our academy and now they have the opportunity this season to make the step up to the under-21s.”
