Gary O'Neil will miss Bristol City's Sky Bet Championship home game against Derby through suspension.
The veteran midfielder was sent off during the 3-2 midweek defeat at Sheffield Wednesday after picking up two yellow cards and serves a one-match ban.
Bobby Reid and Korey Smith are in contention to take O'Neil's spot, with full-back Adam Matthews set to return to the squad after a hamstring problem.
But City will check on Smith, who made his first appearance of the season as a substitute at Hillsborough after ankle surgery, and new defender Joel Ekstrand as they are short of match fitness.
Derby defender Jason Shackell is a new injury absentee with a calf problem and it remains to be seen if Johnny Russell will be able to return from the calf complaint that ruled him out against Ipswich in midweek.
Andreas Weimann and Abdoul Camara resumed training on Thursday with the rest of the Rams squad and could be involved at Ashton Gate.
Weimann has been out since suffering a knee injury in the build-up to the opening game of the season against Brighton while fellow forward Camara has missed the last two matches with a hamstring problem sustained prior to the international break last month.
Derby boss Nigel Pearson has not ruled out either player but admits the trip could come too soon for both men.
