Ghana's Asamoah Gyan almost walked out on the team after he and his family received threats following the young Udinese striker's shaky performance in Thursday's 1-0 win over Namibia.
Coach Claude Le Roy told AFP on Sunday the player and his older brother Baffour had decided to quit the squad, but were persuaded to stay after lengthy talks with him and officials from the national federation.
"I've never seen anything like it," said Le Roy.
Gyan was subjected to tauunts by the crowd at Accra's Ohene Djan stadium after an unconvincing display and a number of poor finishings in Ghana's second Group A match.
Clearly shaken by the crowd turning on him, he was eventually taken off by Le Roy in the 65th minute, his display described as "lethargic and a bundle of nerves" by one local commentator.
After a torrent of abuse from local media and telephone threats he and Baffour, who plays for Saturn in Russia, packed their bags and were set to walk out on Saturday morning.
"They were ready to leave, but I had a long chat with him yesterday morning and everything's okay now, he trained normally in the afternoon and he's still with us," Le Roy reported.
The veteran French coach said he was shocked by the treatment meted out to his star player who scored a penalty in Ghana's 2-1 opening win over Guinea.
"It was more than just unfair criticism. He was threatened, his mother was threatened, his father was threatened. It's the stupidity of the world that we live in."
At the post match press conference on Friday Asamoah Gyan cut a subdued figure, clearly affected by the abuse.
"Personally I'm very sad about what happened. I'm only 22 years old, and when things aren't going well you need encouragement from the crowd.
"I'm very disappointed. I'm sad for what went wrong yesterday but I'm working on my play for the next game and will find my rhythm. I wish I could score five goals a game!"
Asamoah added: "I'm very sad because Ghanaians know what I can do on the field. The downfall of a man is not the end of his life.
"I have played 22 games for my country and scored 15 goals at my age.
"So if things are not going well, I expect encouragement from the fans, not criticism.
"I am working on my play and I will find my rhythm. If things go well it will be better for the team and Ghanaians as well."
Recounting the circumstances around the near walkout, one Ghana player, who did not wish to be named, told the BBC: "We were shocked when we saw Asamoah and Baffour dressed up to leave the national team hotel.
"Some radio stations had been going on all morning with personal attacks on Asamoah and in fact we are all sick of this.
"Players and coaches came in and we ensured that they stayed with the team."
Another Ghana squad member told mtn.football.com: "We came here to fight for our country and a few of the people who are loud are undermining our efforts of trying to win the cup for Ghana."
Gyan scored the fastest goal at the 2006 World Cup, his 68 second strike earning the Black Stars a 2-0 win over Czech Republic in Cologne.
He was then sent off for a second booking in his team's 3-0 second round loss to Brazil.
He scored the first of his 15 international goals against Somalia in November 2003, three days before his 18th birthday.
Ghana, with two wins out of two, are on the brink of a last eight place, with the tournament hosts's needing only a draw in their last Group a game with Morocco in Accra on Monday.
