Great Britain bobsleigher Bruce Tasker will miss the Winter Olympics after suffering a minor stroke on 4 January.
The 30-year-old Welshman, who was due to compete in his second Olympic games in PyeonChang, is expected to make a full recovery.
He was taken to hospital after experiencing dizziness and nausea.
“To me, this was a completely freak occurrence. I was unlucky to be in this situation, but I’m lucky to have come out of it unscathed,” said Tasker.
“I’m set to make a 100 per cent recovery and I already feel as though I’m most of the way there.”
Tasker is hoping to resume with his Great Britain career next season.
Since switching from a career in athletics in 2010 Tasker has competed at six World Championships and a Winter Olympics.
He was part of a four-man crew that achieved fifth-place finishes at three successive global championships, including the Winter Olympics in Sochi. He was also part of the team which won the silver medal winning at the World Cup event in Lake Placid in 2013.
“We are desperately sorry for Bruce to lose his chance of becoming a two-time Olympian so close to the PyeongChang 2018 Games,” added Team GB Chef de Mission, Mike Hay.
