Hereford United striker Leon Constantine broke his nose in a reserve match on Wednesday.
He is unlikely to be considered for tomorrow's game against Dagenham and Redbridge.
Also unlikely to play is Danny Blanchett who received a knock during Tuesday's game against Bournemouth.
Meanwhile manager John Trewick has told BBC Hereford and Worcester that he has noticed a marked rise in the energy, commitment and drive of his squad since the recent arrival of several extra players. He is hopeful that will continue on Saturday against Dagenham.
"Dagenham have had a good start but, as always, it’s about what we do and, if we show the same amount of intelligence and energy, we will be fine.”
Trewick has also spoken about Craig King and a possible extension to his loan at Edgar Street.
"Craig is an all action player, he works really, really hard and that takes peoples eyes. But allied to that he's an intelligent player, he knows what he's doing on the football pitch." Trewick told the OS.
"I've made enquiries about extending the loan and the discussions we've had with Leicester have gone very well.
"I'm very, very hopeful that he'll be joining us for longer than a month."
