Hearts were due to welcome Hibernian to Tynecastle for a 3.00pm start that afternoon but ESPN, the American-based broadcaster, has opted to screen the game nationwide, necessitating the earlier kick-off.
The match is likely to generate huge interest, particularly as it will be the first meeting of Hearts and Hibs fully three months into the campaign. Both clubs harbour ambitions of qualifying for Europe and will see the chance to take points off each other as vital.

Hamilton v Celtic on 24 October (now 12.30pm kick-off live on ESPN);
