From Sam Ross in Stirling by text on 80295: "Thanks a million Walter for everything you've done for the fans and Rangers Football Club. You will always be a Gers Legend. We love you for that."

From swizzo_owen on Twitter using #bbcsportsound: "Now... Can Killie do a Caley and Rangers do a Celtic?"

From thedarrenhudson on Twitter using #bbcsportsound: "Hamilton down a shame for them; but please leave Ali Crawford and Imrie on your way out, thanks."

2149: The title race continues with Rangers keeping the destiny of the SPL championship in their own hands. A Celtic win at Tynecastle or even a draw in Edinburgh will mean a final-day championship decider on Sunday with Rangers travelling to Kilmarnock and Celtic hosting Motherwell.

It's all over at Ibrox and Rangers have moved four points clear of Celtic at the top of the SPL, with Celtic having the chance to cut the gap back to one tomorrow evening against Hearts.

2057: It continues to be a nervy affair at Pittodrie with St Mirren keen to protect what they have against a fairly inexperienced Aberdeen side. Chris Maguire tries to break the impasse with a fierce driven ball across the box but there are no takers for the Dons.

At Pittodrie, there's not much to report with neither side yet able to create a clear-cut chance.
