Sporting Kansas City's Norwich loanee Kamara kicking goals with Sierra Leone foundation
He said the goal celebration was in honour of the foundation he has been setting up for the past few years to help youngsters in his homeland of Sierra Leone.
"The heart-shaped hands is something I have been doing for the last 2½ years," he said.
"I'm building up my foundation in America - the Kei Kamara Heart-Shaped Hands Foundation - so that I can give something back to the people in my country.
"It will provide Sierra Leone kids with school fees and scholarships."
