The most-decorated Olympian in history may just add to his total in the 2016 Summer Olympics in Rio De Janeiro.
Michael Phelps, who retired after the 2012 London Olympics, has his eyes set on returning to the pool, his coach Bob Bowman told the Chicago Tribune. If he does, he'll be looking to increase his record 18 gold medals and 22 medals overall.
"He looks like he is definitely in shape," Bowman told the paper, adding that Phelps has been training several days a week for the past nine months, and that it's likely he'll return for a meet "sometime soon."
Phelps, 28, re-entered the United State Anti-Doping Agency's testing pool last year, which is required in order to compete.
If Phelps is feeling especially ambitious, he could compete this August in the US Championships in Irvine, Ca., which is the selection event for the 2015 World Championships. But even if he doesn't swim in Irvine, Bowman still isn't ruling out an Olympic return.
"If he swims a meet in the next couple months and does well, he will probably give it a shot in Irvine," Bowman said. "But he doesn't have to do that to have a shot at the 2016 Olympics."
