Leeds United have lost forward Ross McCormack for six–eight weeks with an ankle injury.
The Scotland international was carried off during the opening minutes of last weekend’s defeat to Cardiff and a scan has shown that he’s chipped a bone and damaged ligaments.
Whites boss Neil Warnock told the clubs official website: “ It might be that he needs an operation because he's chipped a bone alongside the ligaments.
"It's as bad a twisted ankle as you can get without breaking it."
This injury means that the 26-year-old could miss Scotland’s important World Cup qualifiers against Wales and Belgium in October.
However, this isn’t the only problem that Warnock has as top scorer Luciano Becchio is a doubt for this weekend’s game against Nottingham Forest.
The Argentine forward, who has netted five times this season, hobbled off in Tuesday’s game 3-2 defeat to Hull.
Warnock said: “Becchio banged his ankle. We had to be careful.
"It's alright him carrying on and then we lose him for a month. I didn't want that.”
