Highlights of the weekend's action in the SPFL. In the Premiership, Inverness Caledonian Thistle are in Glasgow to face champions Celtic. Ronny Deila's side inflicted a 5-0 defeat on John Hughes's men on their last visit to Celtic Park in the final match of last season, but the Highlanders had proved themselves capable of causing an upset with their famous Scottish Cup semi-final victory over the Glasgow giants in April. Elsewhere, there's a Tayside derby as Paul Hartley's Dundee make the short trip to play Tommy Wright's St Johnstone. And newly promoted Hearts will take a big support to Dingwall where they meet Ross County for the first time since April 2014.
