Macclesfield earned a point against Luton despite playing with midfielder Peter Winn in goal for 70 minutes.
The Hatters parted company with manager Paul Buckle before the match, but went ahead through Andre Gray after Rhys Taylor parried Jon Shaw's shot.
Taylor was then sent off for fouling Gray and, with no replacement keeper, Winn came off the bench to go in goal.
Winn did well to deny Jake Howells and Gray, before Waide Fairhurst crashed in the equaliser off the post.
Substitute Stuart Fleetwood also forced a save from Winn late on, before rattling the crossbar in stoppage time.
