American sprint legend Michael Johnson is recovering after a mini-stroke, the 50-year-old has revealed.
The former world record holder over 200m and 400m and now a successful TV commentator, said in a post on his official Twitter account on Saturday that he had last week "rather surprisingly suffered what's known as a Transient Ischemic Attack".
Johnson, who claimed the 200m and 400m titles at the 1996 Olympics in Atlanta retired in 2000 after defending the 400m title at the Sydney Games.
He added: "The good news is I'm back at home with my family, cleared of any heart issues and have already made great progress on my road to a full recovery.
"It seems these things can affect anyone, even the once fastest man in the world! I'm no stranger to a good exercise plan and have thrown myself into it with my usual focus and determination."
