Snow and ice enveloping Scotland is threatening to play havoc with the weekend football fixtures.Sunday's horse racing meeting at Kelso has been postponed already. [LNB]And, although there is a chance of milder temperatures on Saturday, the Met Office still expects it to remain cold over the two days. [LNB]Aberdeen, Inverness and St Johnstone are all at home in the Scottish Premier League, with the north east suffering from the worst of the conditions. [LNB]Two SPL matches were among call-offs last weekend, while seven Scottish Football League and Scottish Cup fixtures rescheduled for Tuesday were postponed. [LNB]The SPL says it is monitoring the situation closely, but it leaves member clubs scrambling for indoor facilities, with Edinburgh's Hearts and Hibernian having not trained since the weekend.[LNB] It's not so much the pitch, because we have under-soil heating, it's the roads and surrounding areas St Johnstone manager Derek McInnes In a bid to beat the freeze, St Johnstone players are scattered around four different training centres. [LNB]Perth has been badly hit by the snow and manager Derek McInnes and his backroom staff have had to improvise in order to keep the Saints players ticking over. [LNB]"Monday was a no-no," McInnes revealed. "Perth is at the centre of the worst weather, so we used more local gyms today to take the travelling out of the equation. [LNB]"I was at a Glasgow gym with the boys from the west of Scotland. [LNB]"Tony Docherty was with the boys from Perth and Dundee. [LNB]"Gordon Marshall, the keeper's coach, is with the Edinburgh-based players and Alec Cleland is taking the guys from the Stirling area. [LNB]"We were all doing the same circuits and spin sessions. [LNB]"Tomorrow, we have a five-a-side hall booked in Perth, although some might find it difficult to travel.[LNB]Kilmarnock midfielder Alexei Eremenko was able to train indoors"On Thursday, we have booked the indoor centre at Toryglen, near Hampden, which will give us the chance to have a couple of hours work. [LNB]"On Friday, we will be back at Perth, but it's meant to be minus eight that day! [LNB]"If the weather is still as bad then, it could be difficult getting everyone there again - and if the temperatures don't increase then we will struggle to get the game ahead on Saturday. [LNB]"It's not so much the pitch, because we have under-soil heating, it's the roads and surrounding areas. But we have to try to prepare as best we can." [LNB]Kilmarnock manager Mixu Paatelainen was able to book the Toryglen indoor facility in Glasgow for his players on Tuesday. [LNB]"I wish there were more facilities like this in Scotland," he told BBC Scotland. "We don't have many like this in Scotland and hopefully they build more. [LNB]"Hopefully temperatures will get up a bit. Half a day's rain will take care of the snow, so hopefully that will come Thursday or Friday. [LNB]"We play Motherwell, so the distances are not great. So, even if it is a mid-day call-off on Saturday, we can deal with that and I would like to give it every chance possible."
