Russian skater and Olympic gold medal favourite Evgenia Medvedeva could miss the Grand Prix Figure Skating Final, which takes place in Nagoya; Japan from December 7 to 10 after suffering a crack in a bone in her right foot.
Medvedeva said that she felt pain in her foot before a Grand Prix meeting in Moscow last month but managed to compete using painkillers.
Following the meet, she was diagnosed with a broken foot but still managed to compete in the next meeting, in Osaka, Japan, and had the foot placed in a cast upon her return to Moscow.
However, with it being an Olympic season, she has expressed her determination not to miss any event and said she was undergoing rehabilitation in the hope she will make next month's Final in Nagoya.
Commenting upon the possibility of her missing the Final, the 18-year-old two-time world champion said "If doctors do not allow me to compete in Japan, that would be the worst-case scenario.
"It would be very difficult to watch from the sidelines,
"But I very much hope this will not happen."
Her injury means that she will be unable to compete in the Skate America competition at Lake Placid this weekend.
Athletes on the International Skating Union Grand Prix of Figure Skating circuit will have their last opportunity to qualify for next month's Final at the event.
The competition at the Herb Brooks Arena, which begins tomorrow and concludes on Sunday (November 26), is the sixth and final Grand Prix event of the campaign.
It offers the last chance for skaters to book their place in the Final, which takes place in Nagoya
The men’s event is likely to be a contest between Four Continents champion Nathan Chen of the United States and Russian Sergei Voronov who won the NHK Trophy earlier this month.
However, Adam Rippon of the US, who won the silver medal at the NHK Trophy, could also challenge.
The women's competition is also likely to see a contest between an American and a Russian, as Ashley Wagner and Polina Tsurskava, who both have bronze medals from their first event, will be looking to secure a spot in next month’s final in Japan with a win.
Just like last month’s Skate Canada event, two-time world champions Meagan Duhamel and Eric Radford from Canada, who currently lead the Pairs, will face World silver medalists Aliona Savchenko and Bruno Massot of Germany.
The Canadian pair came out on top on home ice and will be looking to book their ticket to Japan across the border in Lake Placid.
Chinese duo Xiaoyu Yu and Hao Zhang also have a chance of qualifying for the Final.
The ice dance competition will be headlined by brother and sister pair Maia and Alex Shibutani.
Following their victory at Rostelcom in October, they will be hoping to secure top spot on the podium and a place in the Final.
Their closest competition is likely to come from Italian duo Anna Cappellini and Luca Lanotte, who took bronze at the NHK Trophy, and Piper Gilles and Paul Poirier from Canada.
The Pairs and Men’s Short Program will take place tomorrow in the Dance and Exhibition Gala events.
The global prize money for this Grand Prix in Lake Placid is $272,000 (£204,000/€230,000).
