Michael Phelps tells The Associated Press that "nothing is set in stone" as far as a comeback, even though he sent the strongest signal yet by rejoining the U.S. drug-testing program.
Phelps told the AP in an exclusive telephone interview Thursday that he returned to swimming mainly to get back in shape. But he acknowledges it's fun being around his old team at the North Baltimore Aquatic Club.
His coach, Bob Bowman, says he urged Phelps to get back in the doping program to keep his options open. He was tested twice in the third quarter of the year by the U.S. Anti-Doping Agency, but actually rejoined the program near the end of the second quarter.
According to Bowman, Phelps would be eligible to compete again in March.
