The weather has once again wreaked havoc in the Scottish Premier League as games at Aberdeen and St Johnstone were postponed on Friday morning.
Aberdeen were set to host Motherwell at Pittodrie, with new Dons boss Craig Brown having been due to face the club he left in his first game in charge.
Aberdeen confirmed on their website that their game was off as a result of "adverse weather conditions".
A statement from the SPL read: "The Aberdeen v Motherwell fixture scheduled for Saturday December 18 has been postponed.
"The extreme weather conditions currently in the North East and its forecast continuance over the weekend led to police concerns about spectator safety travelling to and around Pittodrie Stadium. A new date will be announced in due course."
Dundee United, meanwhile, were set to travel to McDiarmid Park for the Tayside derby with Saints.
The SPL said: "The St Johnstone v Dundee United fixture scheduled for Saturday December 18 has been postponed.
"The continuation of lying snow and ice in Perth and the forecast weather conditions for the area over the weekend led to concerns from Tayside Police about spectator safety travelling to and around McDiarmid Park.
"We have taken note of these concerns in postponing the fixture. A new date will be announced in due course."
Rangers' meeting with St Mirren had been postponed on Thursday due to significant water damage at Ibrox caused by the recent thaw after severe weather conditions.
