Tasker, who has been receiving treatment for groin and hip injuries, was taken to Wexham Park Hospital, Berkshire, after experiencing dizziness and nausea.

After three days of tests he was subsequently transferred to the Stroke Unit at High Wycombe Hospital before returning home on Sunday (January 7).

The 30-year-old will have further medical checks over the coming days.

Tasker, who was part of the four-man bobsleigh team that could be awarded a retrospective bronze medal from Sochi 2014 following the Russian doping scandal, is confident of a full recovery and that his career is not at risk.

He said: “I’m gutted not to be able to conclude the four-year cycle by going to the Olympics, but I’m very grateful that I’m still fit and healthy.

“I’m still sore but, otherwise, I feel fine.

“While I’m not training, I’m already resuming normal life and the dog hasn’t been missing out on her walks!

“I’m set to make a 100 per cent recovery and I already feel as though I’m most of the way there.

“I’ve been looked after incredibly well by everybody and I’d like to thank my partner Kat and her father [who are both trained doctors], in particular, for their support.

“The same goes to all the medical staff at Wexham and High Wycombe hospitals who looked after me.

"They were absolutely fantastic, as was Dr. George Bownes, [chief medical officer for the British Bobsleigh & Skeleton Association] who has ensured I have received the best care and advice possible since my discharge from hospital."

“To me, this was a completely freak occurrence," he added.

“I was unlucky to be in this situation, but I’m lucky to have come out of it unscathed.

“I have been strongly advised that I don’t compete again this season but the initial prognosis is that I should be able to resume training with the team in a couple of months.

“In the meantime, I’ll still be cheering the team on from my sofa!”

Team GB Chef de Mission, Mike Hay said: “We are desperately sorry for Bruce to lose his chance of becoming a two-time Olympian so close to the Pyeongchang 2018 Games.

“Bruce is an outstanding person and athlete with proven leadership skills and was a hugely valued and popular member of Team GB in Sochi.

“The team has had to overcome adversity already this season and I have no doubt that all of the athletes and their support team have the character and talent to perform at their best in Pyeongchang and do Bruce proud.

“We wish him the very best with his recovery and look forward to seeing him back competing next season.”

The 2018 Pyeongchang Winter Olympics are scheduled to take place from February 9 to 25.
