Alan Tate returns for Swansea after serving a one-match ban at Doncaster last weekend.
His fellow defender Garry Monk will be given as much time as possible to shake off a groin strain but Albert Serran and Kemy Agustien, who enjoyed time at the back against Doncaster, are on stand by just in case.
Joel Ward is expected to keep his place in the Portsmouth side in place of Carl Dickinson, who serves the second match of a three-game ban for his recent red card against Doncaster.
Hermann Hreidarsson is another option for manager Steve Cotterill, but the club do not want to risk rushing the fit-again Icelander back from his career-threatening Achilles injury.
Cotterill was unable to add to his squad ahead of the loan deadline so he is likely to name an unchanged side again.
Striker Danny Webber is still recovering from a cruciate injury and young midfielder Matt Ritchie has extended his loan at Swindon until January.
