Hamilton and Morton drew 1-1 with both sides ending the game with 10 men.
David O'Brien gave the away side a 15th-minute lead, heading David Graham's cross past Hamilton goalkeeper Kevin Cuthbert.
In first half stoppage-time Hamilton were reduced to 10 after Alex Neil was shown a second yellow card for a foul on Scott Taggart.
But the 10 men equalised with nine minutes to play when Ali Crawford fired home left-footed from 12 yards out.
Five minutes later Michael Tidser was shown a straight red card for foul and abusive language by referee Crawford Allan.
Both sides remain without a victory after two games of the season.
