Nethaneel Mitchell-Blake says he is “heartbroken” after losing his Olympic silver medal in the 4 x 100m over CJ Ujah’s failed drug test.
Mitchell-Blake found out on Friday that Britain’s relay team will lose the medals they won at the Tokyo Olympics last August.
Ujah, 27, tested positive for Ostarine and S-23 but says he “unknowingly consumed a contaminated substance.”
“It hasn’t really 100 per cent sunk in yet,” said Mitchell-Blake on Saturday.
“I was happy that some news came out so we can actually get the process going,” said Mitchell-Blake of the decision to strip GB of the medals won by himself, Ujah, Zharnel Hughes and Richard Kilty.
“But then obviously it’s a nail in the coffin saying you’re getting stripped of your Olympic silver medal. It hasn’t really 100 per cent sunk in yet, but when you say it, repeat it and think about it, it’s not a nice feeling.
“We’re all heartbroken by it. It’s gutting for us, the nation, everybody.”
Ujah was tested immediately after the event in August and on Friday the Court of Arbitration for Sport (Cas) concluded that the GB team quartet must lose their medal.
The news was announced along with an apology from Ujah, who blamed a contaminated supplement for the test failure and added that the situation was one he “will regret for the rest of his life”.
Mitchell-Blake added: “I feel like a lot is still yet to be revealed and we just have to let everything play out.
“[Ujah] is my brother, I love him and I know he wouldn’t do anything intentional. It’s unfortunate that things happen of this nature, but he’s taken accountability and that is all you can ask for.
“I accept his apology wholeheartedly. I’ve known him for a long time. We were friends before the sport and we’ll continue to be friends. It has to be heart-wrenching for him, and naturally it’s heart-wrenching for us.”
The penalty imposed by Cas led the UK to lose an Olympic medal a third time at the Summer or Winter Games.
Judoka Kerrith Brown at the 1988 Games in Seoul and skier Alain Baxter in Salt Lake in 2002 lost their bronze medals after testing for a banned substance.
Cas has requested that World Athletics – the sport’s governing body – now make its own considerations, which could include a ban on competition by Ujah.
The substances found in samples of him-Ostarine and S-23-are known as selective androgen receptor modulators (Sarms).
US Anti-Doping (Usada) says that Sarms have “anabolic properties similar to anabolic steroids”.
