Ross McCormack has been ruled out of Scotland's World Cup double header against Wales and Belgium.
The Leeds striker suffered an ankle injury during Saturday's defeat by his former club, Cardiff, and Elland Road boss Neil Warnock today revealed he faced six to eight weeks on the sidelines.
Warnock added on his club's official website: "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."
McCormack scored in the 3-1 friendly victory over Australia last month but was an unused substitute for the qualifying draws against Serbia and Macedonia.
There was more encouraging news from the npower Championship for Scotland manager Craig Levein last night with Blackburn forward Jordan Rhodes and Brighton striker Craig Mackail-Smith, who was left out of the last squad, both on target for their clubs.
Scotland faces Wales in Cardiff on October 12 before the Brussels encounter on October 16.
