Six new signings will be in the line-up - Ryan Hedges, Josh Ezewele, Joe Lea, Tom Eaves, Liam Shepherd and Otis Khan.
Darren said: “I have really enjoyed my first pre-season as manager, and all the players have been giving everything they have in terms of fitness.
“We are all looking forward to visiting Dorchester. Matches such as this allow players to build up their game time, and that is so important as we prepare to make a positive start to the season.”
Tickets for Dorchester (k.o. 7.45) are £10 adults, £6 concessions; £1 under 16s.
The second warm-up is at home to Championship side Bristol City next Saturday followed by an away game on July 18th at Merthyr Town and another away fixture at Salisbury on July 26th.
