Usain Bolt has backed the Court of Arbitration for Sport's decision to uphold the ban on Russian athletes from this summer's Rio Olympics.
Sixty-eight sportsmen and women were accused of doping by the International Association of Athletics Federations last November following a lengthy investigation.
Calls are now being made for Russia's 387-strong team to be completely banned from next month's competition.

As athletics' biggest superstar, Bolt has since responded to and supported CAS' verdict.
According to the Guardian, he said: "This will scare a lot of people and send a strong message that the sport is serious about cleaning up.
"For me if you have the proof and you catch somebody I definitely feel you should take action. If they feel like banning the whole team is the right action, then I am all for it.
"Rules are rules and doping violations in track and field are getting really bad, so thumbs up."
Bolt was also asked for his view on banning Russia from the Olympics altogether, to which he replied: "That's a tricky question.
"I don’t stress about these things, I leave it up to the big heads to make this decision. These are sideshows, and if you get caught up in these things as athletes then you lose focus of the goal in hand.
"I have to focus on me going there and defending my titles."
The International Olympic Committee are due to have an emergency meeting on Sunday to discuss the prospect of a blanket ban for Russia.
Where Bolt is concerned, the eccentric Jamaican saw victory in the 200m at the London Anniversary Games on Friday night, running an impressive 19.89 seconds.
The 29-year-old raised concerns when he missed Jamaica's trials earlier this month but stormed to victory ahead of Britain's Adam Gemili, who finished third and clocked a season's best of 20.07.
The Rio Olympics now awaits Bolt, who will seek to defend his 100m, 200m and 4x100m relay titles.
