Swindon have no fresh injury worries as they look to play for the first time since December 21.
The Robins saw League One matches called off against Leyton Orient and then Colchester over the festive period due to waterlogged pitches on the back of an emphatic 5-0 win over Tranmere.
Alan Navarro (medial ligaments) is ready for a return to action for the first time since October although Paolo Di Canio could name the same side that put Rovers to the sword.
John Bostock and Danny Hollands are both coming to the end of their loan stays at the County Ground from Tottenham and Charlton respectively but are set to be involved.
Defender Jay McEveley remains out having undergone knee surgery while Paul Benson is on loan at Pompey and unable to feature against his parent club on New Year's Day.
Portsmouth are without Izale McLeod.
The club's top scorer picked up a fifth caution of the campaign during Saturday's 2-1 defeat against Yeovil and serves a one-match ban.
McLeod was replaced at half-time following an ineffective performance and his replacement Ashley Harris could be handed a start against the promotion-chasing Robins.
Skipper Brian Howard will be assessed ahead of the game as he too was substituted at half-time after complaining of a groin problem.
Experienced defender Jon Harley is available for selection after sitting out his one-game suspension against Yeovil and is expected to return to the defence.
Pompey have gone 12 games without a win and are in 21st place in the table, two points adrift of safety.
