MOSCOW -- Japan's Yuzuru Hanyu won gold at the Rostelecom Cup, the fifth of six Grand Prix figure skating events, despite an ankle injury that left him on crutches after the competition.

Hanyu, the Olympic gold medallist , started strongly on Saturday with two clean quads and appeared to be his usual assured self, but he stepped out of his second pass at a quad toe loop then fell on a triple and singled an axel.

With his ankle wrapped in a bandage, Hanyu hobbled into a news conference and said he had aggravated a previous ankle injury in the morning practice.

He had considered dropping out, he said, but "I really love skating here. I really wanted to skate this program."

The injury leaves him uncertain about whether he'll compete in the Japanese nationals or in the Grand Prix Final in December, Hanyu said.

His free program total score of 167.89 was more than 20 points off his season best, but it was nearly 10 points ahead of Georgia's Morisi Kvitelashvili, who landed three clean quads to make his first Grand Prix podium appearance.

"I really managed to execute everything I planned," Kvitelashvili said. "Not everything went smoothly."

Japan's Kazuki Tomono took bronze, moving up from fourth place after the short program. Alexander Majorov of Sweden, who was third after the short program, had trouble on almost every jump after his opening quad and finished the free skate in 10th place.

Tomono said he had a bad case of the nerves at the beginning of his free skate and "was losing to myself," but then regained control to win his first Grand Prix medal.
