Pompey will be without Conor Chaplin at Yeovil.
But the Blues have been boosted by the news Danny Hollands has returned to training.
Chaplin has picked up a ligament strain, which will rule him out of the trip to Huish Park.
Pompey are confident the injury is not a major problem, however.
Hollands will also miss tomorrow’s game, but is expected to step up his recovery next week from a broken leg.
The midfielder fractured his fibula in the FA Cup clash at Ipswich last month.
