See 10-man Celtic drop points in 1-1 draw with Hamilton
Eamonn Brophy scored with 17 minutes left to play to give Accies a share of the points.
Watch highlights of the 1-1 draw between Hamilton Accies and Celtic in the Scottish Premiership.
A superb strike by substitute Eamonn Brophy gave Hamilton a share of the points against league leaders Celtic, who played the majority of the game with 10 men.
Hoops striker Leigh Griffiths scored from the spot in the 35th minute after being brought down by Dougie Imrie before Parkhead defender Dedryck Boyata was shown a red card by referee Craig Thomson for a last man tackle on Carlton Morris just outside the box.
In the 65th minute, Accies goalkeeper and skipper Michael McGovern saved a Griffiths penalty after Thomson had penalised defender Ziggy Gordon for wrestling with Celtic counterpart Mikael Lustig at a corner.
Brophy - who had scored in the 8-1 defeat at Parkhead in January - came on for Darren Lyon in the 70th minute and levelled four minutes later with a drive from inside the box for a share of the spoils which took Celtic seven points clear of Aberdeen, who host St Johnstone on Saturday.
It was certainly an eventful evening at New Douglas Park.
