RIO DE JANEIRO (AP) - Don't expect speculation about Michael Phelps' Olympic future to die down anytime soon. Especially with his Olympic roommate and swimming rival Ryan Lochte stirring speculation about Tokyo.
Lochte said Friday on NBC's "Today" that his rivalry with Phelps will "definitely" have another chapter at the Tokyo Games in 2020.
Lochte says: "I guarantee he will be there."
Phelps has already come back from retirement once, but has said he plans to retire after Rio. He's already won four golds here and has the chance for two more.
Phelps easily beat Lochte and the rest of the field Thursday night in the 200-meter individual medley, besting his American rival by nearly 3 seconds. Lochte placed fifth.
