Crystal Palace's FA Cup defence got off to a shaky start as the Eagles trail sixth-tier Macclesfield in the third round.
Palace dominated possession for most of the first half but struggled to carve out any clear-cut opportunities.
The Premier League outfit were rocked minutes before half time after conceding the opener.
Macclesfield's Paul Dawson climbed highest to head into the net from Luke Duffy's free-kick to send Moss Rose into delerium.
Could the Silkmen hold on for one of the biggest-ever FA Cup upsets?
