The green and whites face the trip to Cheshire before welcoming Colchester United to Huish Park on Easter Monday.
Ahead of a busy fixture schedule, Marmon told iFollow Glovers that he has a virtually full fit squad to choose from.
“Omar has joined in again at training and is looking pretty fit and Pattison is up for it as well. There’s only Rhys Browne now who’s three or four days away, so the whole squad is pretty much available.”
The winger has been sidelined with a hamstring injury since limping out of the 3-0 defeat at Port Vale in March, but is back running in training.
Elsewhere, Josh Grant (achilles) remains back at parent club Chelsea to receive further treatment whilst there looks set to be a return to the matchday squad for Francois Zoko who’s been absent since the end of March.
The experienced trio of Carl Dickinson, Craig Alcock and Zoko have all missed out in recent weeks, with Town’s boss providing an explanation.
“Carl has been training at Port Vale after we gave him the opportunity to take a chance and get a new club for next year. He has a contract here but if he gets the opportunity to get a contract closer to where he lives then I think he’s looking for that.
“Craig Alcock has been involved with the Academy as he’s looking at his coaching badges and actually, it’s looking like Francois will join us in the squad to travel to Crewe.
“He’s trained very well this week so we’ll look for his experience on the bench.”
