VAR will be used in Scottish football for the first time this weekend - across the six matches in the cinch Premiership.
The first of those fixtures takes place at Easter Road this evening when Hibernian play St Johnstone, kick-off 7.30pm.
William Collum has been appointed by the Scottish FA as the VAR for that match, with Graeme Stewart the assistant VAR.
The on-field referee is Kevin Clancy, with assistant referees Alastair Mather and David Doig. The fourth official will be Graham Grainger.
