BARCELONA, Spain (AP) -- Michael Phelps keeps saying he has no plans for a swimming comeback.
Yet he's leaving the door open to change his mind in time for the 2016 Olympics.
As Phelps put it, "I don't know what I'm doing tomorrow."
Phelps spoke Monday in Barcelona to The Associated Press and other international media organizations in a series of one-on-one interviews set up by his sponsor, Speedo.
While Phelps quickly shot down questions about whether he's done any clandestine training for a possible comeback, he wasn't as adamant as he's been in the past about his swimming career ending for good at last summer's London Olympics.
Asked by the AP, yes or no, whether he'll compete at the Rio Games, Phelps says he hasn't planned that far ahead in his life.
