Burnley's top scorer Andy Gray will be out of action for two months after breaking three metatarsals in his right foot during the 2-1 win over Leeds.
Gray joined Burnley from Sunderland in the summer
Gray was hurt soon after scoring Burnley's second in Tuesday's game - his 10th goal of the season.
"It is obviously a blow to lose Andy as he has been in exceptional form since he came here and he's a terrific team player," said boss Steve Cotterill.
"However it gives an exciting chance to a young prospect in Kyle Lafferty."
