This is because first team skipper Chris Froud misses the game due to a family wedding.
A replacement at the top of the order was set to be decided by Froud and Coombs last night.
The newly-promoted Bountymen have so far won both their away games this summer at Sarisbury and Fawley.
Last weekend, Basingstoke suffered a wash-out as overnight rain flooded May’s Bounty and so their early season top-of-the-table clash with Liphook and Ripsley was cancelled.
Once again this weekend it is a journey into the unknown for Basingstoke as they head to Dorset to face a side relegated from the Premier Division at the end of last summer.
Froud said: “They have signed a lot of players so we are expecting them to be strong, but we feel if we play well we would fancy ourselves to beat anyone.
“It is a bit of lottery at the moment as no one has played a lot of cricket.”
Basingstoke’s second XI are at home to Alton II in Division Three, looking for their third league win on the trot.
