Arsenal youngster Lansbury has been laid low by a stomach bug this week and fellow midfielder Cleverley, on loan from Manchester United, suffered a knee injury during the midweek win over Sheffield United.
Buckley should be involved, though, after recovering from a thigh strain.
The winger is likely to be on the bench for the first time since completing his January switch from Rochdale.
Former Blackburn and Birmingham centre-half Martin Taylor made his debut against the Blades with Adrian Mariappa moving to right-back and Lee Hodson dropping out.
Teenager Hodson was rested from the matchday squad and will hope to make the bench at Oakwell.
