Crewe boss Dario Gradi must decide whether to bring back influential midfielder Lee Bell for the visit of Bradford.
Danny Shelley was drafted in against Stockport while Bell served a one-match ban. With Shelley marking an impressive first start of the season with a stunning free-kick goal in the 3-3 draw, Gradi could find it difficult to return to his regular midfield trio.
That could mean either Luke Murphy or Ashley Westwood being axed to accommodate Bell, who had been an ever-present in the team before the game at Edgeley Park.
Westwood, defenders Danny Blanchett and Adam Dugdale and goalkeeper Rhys Taylor have been receiving treatment for knocks but are expected to be available for selection.
Bradford manager Peter Taylor is hoping central defenders Rob Kiernan and Luke Oliver can prove their fitness.
Oliver has been nursing a hamstring problem in recent weeks, while Kiernan (hamstring) is the latest centre-half to sustain a niggling injury after being withdrawn late on in last week's home win over Hereford.
Fellow central defenders Shane Duff (Achilles) and Steve Williams (groin) are both back in training, but are not ready for first-team action.
Taylor expects midfielder Tom Adeyemi to shake off an ankle injury, while defender Lewis Hunt is making good progress following a knee ligament injury.
Long-term absentees, defender Simon Ramsden (calf) and midfielder Michael Flynn (hernia), expect to be back in action by early February.
