Worrall, borrowed from Rotherham at the start of the month, is still recovering from a groin problem which has left him on the sidelines since August but he has been training this week and may make Lee Johnson's squad.
Johnson declared the rest of his players as all "fit and raring to go" as they try to win on the road in Sky Bet League One for the first time since November.
Defender Cliff Byrne could come back into Johnson's thinking after returning to the north-west despite training with Ross County ahead of a possible move there earlier this week.
