The Stags held their own for the first half of their first game against a strong Darlington II's and coaches Sammy Hutton and Gary Miller will be looking to build on that.
Its expected that Horden will also field some of their younger players.
Quite who Sammy and Gary have to pick from depends on first XV requirements. Peter Hodgson is out with his badly broken nose and Tommy Barff is still limping after getting injured in Saturday's warm up.
