Portsmouth midfielder Liam Lawrence is expected to be fit enough to make the squad for the trip to Leicester.
Lawrence returned from three weeks out with a calf problem by coming on as a 59th-minute substitute in last Saturday's 0-0 draw against Middlesbrough.
He suffered no recurrence of the injury during the match but picked up a niggle in training this week which he should overcome.
Boss Steve Cotterill has no other new injury or suspension problems and has a rejuvenated squad to choose from as this was the first time in three weeks they did not have a midweek game.
Defender Aaron Mokoena, who has been dropped by South Africa for their 2012 Africa Cup of Nations qualifier against Egypt on March 26, is set to continue on the bench.
Forward Danny Webber has stepped up his recovery from a year on the sidelines with anterior cruciate ligament damage but is nowhere near ready to return.
