A second-half double from Jerry Bengston wasn't enough to hand Honduras only their second ever win in the Olympic Games as 10-man Morocco held on for a 2-2 draw at Hampden Park.
The Africans enjoyed the better of the opening period and went ahead seven minutes before half-time thanks to a sweetly struck volley from Abdel Barrada.
Honduras responded excellently after the break though and were level on 55 minutes when Bengston tapped home Maynor Figueroa's shot from close range.
Bengston then scored again from the penalty spot, but the lead only lasted two minutes before Zakaria Labyad equalised with a scooped effort that eluded Jose Mendoza.
Zakarya Bergdich was then shown a red card for kicking out at Mario Martinez with 19 minutes remaining but Honduras couldn't take advantage of their man advantage as the points were shared.
With World and European champions Spain to come later in the group, it was imperative for both sides to get their campaign off to a good start and that resulted in a relatively cagey opening with few clear-cut chances.
Houssine Kharja had the first serious effort on goal just after the half hour but his powerful header was excellently turned away by Mendoza.
It took Morocco only a further five minutes to break the deadlock though as Labyad's cushioned header fell perfectly for Barrada to fire in first time from just outside the area.
Honduras should have been level almost immediately as Bergdich was caught in possession in a dangerous area but Andy Najar couldn't turn Martinez's cross in from a couple of yards out.
The equaliser did arrive shortly after the break though as Figueroa's tame effort was redirected past Mohamed Amsif by Bengston and Luis Suarez's men had turned the game on its head nine minutes later when referee Pavel Kralovec adjudged that Johnny Leveron had been pulled back by Yassine Jebbour in his attempt to meet Arnold Peralta's teasing cross. Bengston stepped up again and coolly slotted the penalty straight down the middle of the goal.
The Central Americans' lead lasted only two minutes though as more good combination play between Barrada and Labyad this time found the later inside the area and his lofted effort floated over Mendoza and into the net.
And despite the Honduras' numerical advantage it was Morocco who had the best chance to win the game as Jebbour fired wastefully into the side-netting when one-on-one with Mendoza.
