Campbell-Brown to return at Worlds
Campbell-Brown was recently cleared to return to competition by the Court of Arbitration for Sport after appealing a two-year ban reccomended by the International Association of Athletics Federation.
Her return to action means the 2004 and 2008 Olympic gold medalist may compete at the Commonwealth Games this summer.
Also on the 23-person roster headed to Sopot are sprinting stars Shelly-Ann Fraser-Pryce and Nesta Carter.
Here is the full press release by CAS on Campbell-Brown cleared of doping.
