The striker is set to take a break from international football claiming he has never got over missing a last-minute spot-kick in a quarter-final the Black Stars went on to lose
The Ghanaian, who is on loan with Al-Ain from Sunderland, famously missed a penalty in the closing minute of the quarter-final clash with Uruguay after Luis Suarez handballed on the line.
Gyan also recently missed another crucial penalty in the semi-finals of the Africa Cup of Nations in a 1-0 loss to Zambia.
The 26-year-old has since announced that he is taking an indefinite break from international football but vows to come back mentally stronger.
"Firstly, it's important I express my sincere apologies to my country," he said on his personal Twitter page. "I never intended to make a decision like this early on in my career.
"Psychologically I am down. As you can imagine it's been very hard for me mentally to miss two important successive penalties for my country.
"And because of this a break to recoup my thoughts and emotions will aid me to come back bigger and mentally stronger.
"I never fully recovered from the 2010 World Cup and now 2012 Afcon. I want my country to know I love playing for them and I wouldn't be who I am without them.
"I would like to ask for prayers and support from Ghanaians to help me to come back with a renewed strength to continue serving my country."
New Sunderland manager Martin O'Neill has recently expressed his desire to bring Gyan back since his arrival at the club.
