Ryley Towler could be set for a fresh spell on the sidelines after suffering an injury 44 minutes into Bristol City Under-23s clash with Severnside neighbours Cardiff City.
Robins defender Towler has been out since January with a back problem, which Nigel Pearson has previously said was linked to his age, as the 19-year-old continues to fill his body out.
Towler started in central defence alongside Duncan Idehen in South Wales but was unable to complete the first-half after he dropped to the turf after winning a defensive duel on his own byline. The teenager received treatment for around a minute before he was taken off, with what appeared a groin problem.
