(The Sports Xchange) - Jarryd Hayne announced his retirement from the National Football League on Sunday after playing one season with the San Francisco 49ers. Hayne, a running back, said the opportunity to play rugby sevens for Fiji in this year's Rio Olympics prompted the decision. "I am retiring from the NFL because the Fiji Rugby Sevens team reached out to me about the opportunity to join the team for the upcoming Olympics, and I simply could not pass that chance up," Hayne said in a statement.
