Comebacks are on tap in the first Diamond League meet of the Olympic season in Doha on Friday.
South African Caster Semenya, the 2012 Olympic 800m silver medalist, is set for her first Diamond League race since 2014.
American Walter Dix, the 2008 Olympic 100m and 200m bronze medalist, hasn’t contested a Diamond League since 2013.
And France’s Teddy Tamgho, the 2013 World triple jump champion, returns to Doha after rupturing an Achilles tendon at the Qatar capital last year.
Those are some of the bigger storylines in a meet that lacks the presence of Usain Bolt, Justin Gatlin, Allyson Felix or Shelly-Ann Fraser-Pryce.
