Michael Phelps, the Olympic swimming superstar and burgeoning golfer, was in Barcelona over the weekend, where he popped in on the swimming world championships and participated in the dedication of a mural in which he is featured.
As eye-catching as the mural is, what really stands out in the photo of Phelps at the dedication is that big black boot on his right foot.
Apparently, Phelps was nursing a stress fracture in that foot, then exacerbated it while playing golf – perhaps, he believes, by stepping into a hole.
"He hit his foot somehow in the house and then he did that tournament when he walked about 20 miles and got a little stress fracture," Phelps' coach Bob Bowman told the Associated Press . Bowman didn't specify which tournament he was referring to.
"Golf really is a dangerous sport," Phelps joked. "The good thing is, I only have to pack one shoe."
Phelps also recently starred in the most recent season of ''The Haney Project,'' in which he received instruction from PGA instructor Hank Haney. And, of course, he owns 22 Olympic swimming medals.
Though he hasn't yet publicly commited to a return, speculation remains high that Phelps will jump back in the pool for the 2016 Olympics in Rio de Janeiro. Bowman doesn't believe the foot situation will make any difference in Phelps' potential return.
"I think he'll be fine,'' Bowman told the Golf Channel . ''He can wait that out. I don't think that's imminent."
