Ben Chorley's injury-time equaliser earned Leyton Orient a point away to Huddersfield Town.
Alan Lee gave Huddersfield the lead, heading in Jack Hunt's cross, before Hunt himself drove in from distance.
Jamie McCombe was sent off for the home side in the 84th minute after an off-the-ball incident with George Porter.
Orient's Kevin Lisbie headed in Dean Cox's corner seconds later before the turnaround was complete when Chorley smashed home from close range.
The result extends Huddersfield's unbeaten league run to 35 games - a record outside the top flight in England.
VIEWS FROM THE DRESSING ROOM
Leyton Orient boss Russell Slade told BBC London 94.9:
"All afternoon I felt that we deserved something out of the game.
"Even in the first period I thought we created one or two wonderful opportunities for an away side.
"Fair play to the lads, we stuck to our guns, we kept going and we got something for it."
