Cheltenham are the visitors to Fratton Park on Saturday, giving head coach another guaranteed selection headache as he weighs up his options.
Given the squad’s strength and depth – irrespective of injuries picked up by Tom Lowery and Paddy Lane in recent weeks – the likes of Zak Swanson, Ryley Towler, Terry Devlin and Ben Stevenson have had to spend time in the stands.
Meanwhile, Sean Raggett has not been able to nail down a starting spot as competition for starting places intensifies following a recruitment drive that has seen 13 new arrivals delivered to date during the current transfer window.
