First Division leaders Morton maintained their eight-point advantage over Partick Thistle by coming from two goals down to draw with the Jags.
Chris Erskine converted Aaron Sinclair's cross to give Thistle a ninth-minute lead.
Steven Craig headed the visitors' second just after the break but Peter MacDonald pulled one back with free-kick from 30 yards that crept into the net.
And MacDonald levelled from the penalty spot on 81 minutes after Hugh Murray had handled in the area.
Murray was then sent off for picking up a second booking as the match ended all square.
