The Colombian Football Federation on Monday confirmed coach Hernan Dario Gomez was quitting his post amid a furore sparked by his hitting a woman who insulted him in a bar.
Gomez had already offered to resign on August 9 after reports emerged of his striking a woman outside a bar but several players urged him to reconsider, criticising his behaviour while offering their support in an open letter.
A Federation statement indicated that Gomez was "irrevocably" confirming his initial decision to stand down.
After news of his contretemps with his critic first emerged Gomez said he felt "mortified" and offered a profuse apology for his assault.
He added his action "shames me in front of my mother, my wife and every single woman in my family and in my country."
Players offered support and said they were ready to act as "standard bearers for the cause of non-violence against women.
Gomez, who in the past month had been working as an observer for FIFA at the under-20 World Cup in his homeland, led Colombia to the quarter-finals of the recent Copa America, where they lost to Peru, and also took Ecuador to the World Cup finals for the first time in their history in 2002.
