The Ukrainian version of the tribuna.com sports website reported:, external "A Russian TV correspondent called for Verniaiev. When the man from Donetsk [Verniaiev] came up to the correspondent and saw the microphone with 'Rossiya [Russia]' on it, he demonstratively turned around and left for the locker room, without saying a word."
Let's be honest... we'd all post a celebratory Facebook picture if we won Olympic gold.
It's better than a picture of somebody else's kids/cat/lunch...

Image source, .BBCPlotting out the Deodoro medal chase each night ready for the next day is getting more and more difficult.
Today I'm thinking it's shooting for 16:15 BST where Jen McIntosh should be in the women's 3 position rifle final.
I'll ask Jen and organisers to get things wrapped up quickly, hop a bus to canoe slalom where David Florence and Richard Hounslow will probably be in the C2 final at 18:15 BST. Then Fiona Pennie should make the K1 final at 19:00.
Bus. Rugby sevens. Bronze and gold medal matches from 22:30 BST, Team GB will be in one of them. And finally a walk to hockey, where GB's women are in action at 00:30 BST.
If it's half as dramatic as yesterday then it'll be a treat of a day.

Pure heartbreak for Dutch dressage rider Adelinde Cornelissen.
She was forced to retire on 19-year-old Jazz gelding Parzival after only a few movements on Tuesday and she's explained why on her Facebook page., external
Parzival, who helped Cornelissen win two medals at London 2012, had been bitten by an insect on his face and had developed a high fever, just a day before he was due to perform.
After extensive treatment from a vet, eventually he returned to normal but his rider decided she couldn't let him compete.
“My buddy, my friend, the horse that has given everything for me his whole life does not deserve this…. So I saluted and left the arena,” she wrote.
Without a travelling reserve, the Dutch team will now compete as a three-piece.

Rio, be prepared.
British gymnast Brinn Bevan has told BBC Radio 5 live how he "battled back" from a double leg break to fulfil the promise he made to his dying father - to compete at an Olympic Games. Bevan, who broke his left tibia and fibula after landing on a concrete floor, says he "never lost sight" of his goal to go to Rio; to "live up to [his] promise".

Today we're asking for your thoughts on the greatest ever Olympian...
Nickie Harper-Williams: Usain Bolt. Because I trained in track and field as a teenager, got to represent my county...I can understand the training he goes through.
Daniel Brown-Bennison: For me it has to be Daley thompson or Sir Steve Redgrave. I think those events take its toll on the body a bit more than sprinting or swimming does.
Kevin Thomas: Emil Zatapek, Jesse Owens, Usain Bolt, Michael Phelps are my top ones. But Mo Farah if wins his races becomes greatest Olympic long distance runner.
Swimming

The American swimmer bleached platinum blond before the Games.
One problem. Even with a swim cap on the chlorine in the pool is slowly turning his new style a green-ish tinge.
The big man seems unabashed with his unintentional look.

Bear with us...
Apparently depth of a pool can determine how fast swimmers can swim, hence all the records tumbling in the aquatic centre in Rio.
"A fast pool typically has at least three meters of depth to it,” says Teri McKeever, head coach of the University of California’s women’s swimming team, and who served as the U.S. head coach at London 2012. “The deeper the pool is the better, because the splash or the turbulence and everything takes longer to get down to the bottom and then it doesn't ricochet back up into the swimmers.”
The atmosphere in the pool arena matters too, because of the psychological effect it can have on competitors.
“I think it is a fast pool,” said American Connor Dwyer after winning bronze in the 200-meter freestyle on Monday. “It’s kind of like our trials pool: good energy in the stadium with no diving well in there. So you can definitely hear the noise in the surrounding pool.”
So now you know... Pools can vary in "speed".
Football
This image summed up Brazil's feelings after the opening two games in the men's and women's football competitions.
The hosts had been promised an all-out assault for gold on two fronts, but only the women (5-1 winners against Sweden and 3-0 winners against China) seemed to be delivering.
The men, by contrast, had recorded back-to-back goalless draws against South Africa and Iraq.
Neymar and co. finally clicked into gear last night though. walloping Denmark 4-0. Manchester City signing Gabriel Jesus got on the board.

Basketball

The Aussies led 54-49 after the second quarter and the United States were facing the prospect of their first loss since going down to Argentina in 2004.
The rebooted Dream Team came through to win in the end with the Australian-born Kyrie Irving scoring 19 of the United States points.
As pundit Diana Taurasi said on American television, it was a reminder that "other people play basketball too".

Capybaras are about four foot long and ten stone in weight. They pose no risk to the golfers. And if they listen out for calls of 'fore!' the same should be true in reverse.
