Yohan Blake is set to run the 100 metres at the Diamond League meeting in Lausanne where he clocked a career-best 9.69 seconds last season.
Organisers of the Athletissima meeting say Blake is entered in the 4 July race alongside Tyson Gay and Justin Gatlin of the US, and Jamaican team-mate Asafa Powell.
Blake tied with Gay as the second-fastest man in history, behind Usain Bolt, when he beat the American at Lausanne last August.
Organisers say Blake, who is sidelined by a hamstring injury, "wants to come only if he will be in the fittest condition". Bolt typically runs the 200m at Lausanne but is not yet confirmed as a starter.Reuse content
