Reid missing for Robins
Bristol City will be without midfielder Bobby Reid when they host high-flying Leyton Orient.
The 20-year-old has not been able to train since Friday due to an ongoing hamstring injury and will miss out on the Ashton Gate clash with the league leaders.
But head coach Sean O'Driscoll has been boosted by the news that left winger Joe Bryan has recovered from a 24-hour bug and is available having returned to training on Sunday.
Despite their 1-0 defeat to Sheffield United, City are unlikely to make many changes but centre-back Derrick Williams and midfielder Simon Gillett will hope for recalls.
Leyton Orient could remain unchanged from Saturday's impressive win at Swindon when they head west again.
Boss Russell Slade has no fresh injury concerns for the trip but could hand Millwall loanee Josh Wright a first start should he opt to shuffle his pack.
Mathieu Baudry will be hoping for a second successive start after winning his place back from Gary Sawyer following a three week lay-off.
Shaun Batt continues to wait patiently for a run in the side, despite scoring nine goals already in all competitions, but the form of attacking trio Dean Cox, David Mooney and Kevin Lisbie is likely to mean another place on the bench for the former Millwall man.
