Leeds United boss Neil Warnock says he will be without injured striker Ross McCormack for "six to eight weeks".
And now he is sweating over the fitness of top scorer Luciano Becchio ahead of Saturday's home Championship clash against Nottingham Forest.
McCormack was carried off in the early stages of last weekend's defeat at Cardiff and a scan revealed he has damaged ligaments in his ankle.
But the Scotland international, 26, also chipped a bone and may need an operation later this week.
Argentine striker Becchio netted his fifth goal of the campaign in United's 3-2 home defeat by Hull City on Tuesday, before hobbling off with an ankle injury in the second half.
Afterwards, 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.
"We're already without Ross and we know he will be out for six to eight weeks now.
"It might be that he needs an operation on Friday because he chipped a bone alongside the ligaments.
"It's as bad as you can get from a twisted ankle without breaking it."
