Neil Warnock makes his bow as Cardiff manager in the Severnside derby with Bristol City contemplating whether to hand debuts to his new signings.
Warnock has signed four free agents - Sol Bamba, Junior Hoilett, Marouane Chamakh and former England international Kieran Richardson - since replacing the sacked Paul Trollope during the two-week international break.
The quartet's fitness will be assessed with defender Bamba and winger Hoilett the most likely to feature.
Matthew Connolly is available after serving a one-match suspension and Anthony Pilkington (thigh), Aron Gunnarsson (calf) and Rickie Lambert (hamstring) will all be checked.
Bristol City are expected to welcome Mark Little back after hamstring trouble.
Right-back Little missed the 2-1 victory over Nottingham Forest before the international break after hobbling off in the previous game against Leeds.
Forward Gustav Engvall is also available after picking up a knock while on duty with Sweden Under-21s, and former Cardiff defender Adam Matthews and midfielder Korey Smith built up their fitness for the Robins' under-23 side this week.
Lee Tomlin has served a one-match ban and should renew his strike partnership with the on-loan Tammy Abraham, whose two goals on his England Under-21 debut this week took his total to 13 in 15 games for club and country this season.
