Regular skipper Linden Dovey is available, so striker Mann will take the armband.
Assistant manager Gerry Oldham is missing the game due to a wedding.
Forward Mark Magee is also attending a wedding, while Nick Rhodes is still sidelined by a hamstring injury.
A late decision will be made on Paul Fahy, who has been struggling with tonsillitis this week.
Striker Greg Peel could make his first league appearance, against the club he left to join Evesham in the summer.
United rounded off their pre-season programme with a comfortable win at Dorchester Town last Friday, followed by a team social later than night.
The only player who has been with Evesham throughout the summer yet to sign is Sean Brain, but Collicutt is keen to add him to the squad, although he may initially be sent out on loan to a team one step down.
Larkhall, who knocked Evesham out out in the play-off semi-finals three seasons ago, are managed by Phil Bater. They finished 13th last year.
