Olly Lancashire headed home in injury-time to salvage a point for Walsall against 10-man Leyton Orient.
Lancashire rose highest to meet Richard Taundry's corner but the Saddlers stay in the League One relegation places.
Orient had gone in front when Dean Cox scored his eighth of the season after a long clearance from keeper Marek Stech.
But Jimmy Smith and Kevin Lisbie wasted chances to double the lead before sub Solomon Taiwo was sent off for a two-footed tackle on Florent Cuvelier.
VIEWS FROM THE DRESSING ROOM
Leyton Orient manager Russell Slade told BBC London 94.9:
"We will appeal that decision [the sending off] straight away - it was a ridiculous decision.
"We could have won the game four or five today. We have had a stonewall penalty turned down.
"We got ourselves in front and its just a travesty because the boys worked so hard to get a result.
"I would say we should have finished the game off because we looked in control for the majority of it."
