Hearts face Uefa action over fans' Anfield 'invasion' during Europa League clash The salaries for a small number of the Edinburgh club's top-earning players remain outstanding. Hearts said they were seeking to swiftly resolve the issue, which has resurfaced after a number of similar delays last season. Last term three straight months of delayed player wages prompted an official complaint from the players, via union PFA Scotland, to the Scottish Premier League, but action was averted in January after Hearts met the demands imposed. However, the issue reared its ugly head again in March, when players and staff received their salaries 12 days late. Hearts attributed some of last term's delays to logistics transferring the funds from Lithuania, where majority shareholder Vladimir Romanov is based. The latest delay comes after a month which featured a glamour Europa League tie with Liverpool, while all 12 Clydesdale Bank Premier League clubs are awaiting the latest instalment of television revenue amounting to £300,000 per club. 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 on Tuesday 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 Oct 12 before the Brussels encounter on Oct 16. Rangers fans could be asked to register their interest in a share issue as early as next month. The Rangers board have in recent weeks appointed Cenoks Securities as brokers for their initial public offering (IPO) while Capita have been contracted to deal with supporters enquiries and for registration purposes. Green said: "What we plan to do now in the next few weeks is put an information pack together and in early October there will be further information put out to fans and they can register their interest." Rangers manager Ally McCoist branded their Ramsdens Cup exit to Queen of the South "a sore one" after suffering their first defeat of the season. The Light Blues were sent crashing out of the tournament after a dramatic penalty shoot-out decided the third round tie at Ibrox, which was still deadlocked at 2-2 after extra-time. McCoist said: "It's a sore one, that's for sure. It's really, really disappointing to get beat and knocked out in the manner we did. I don't think it's a wake-up call. It's a big disappointment. Queen of the South's reward for knocking out Rangers is a home tie against Arbroath in the semi-finals. Partick Thistle travel to face Cowdenbeath in the other match.
