The American swimming great Michael Phelps, the most decorated Olympian of all time, is coming out of retirement.
Phelps, who turns 29 in June, rejoined the U.S. Anti-Doping Agency's drug testing programme last November, a clear signal that he could be considering a return to the swimming pool in time for the Rio de Janeiro Games in 2016.
Phelps retired from competitive swimming after winning four gold and two silver medals at the 2012 London Olympics to take his career tally to 22, 18 of which were gold.
He had repeatedly said before the London Games he would not contemplate a comeback after he retired, and his coach downplayed any suggestions Phelps was considering a return to compete at what would be his fifth Olympics in Rio.
His comeback meeting will be in Arizona next week.
