Roger Federer fell outside the top 10 for the first time since 2002 on Monday -- the result of an injury-filled 2016.

The Swiss player reinjured his knee in a semifinal loss to Canada's Milos Raonic at Wimbledon in July. He lost to Raonic in five sets.

Soon after, Federer announced he would miss the Rio Olympics and the rest of the year in a bid to recover for 2017.

The 17-time grand slam winner was due to play mixed doubles at the Olympics with Martina Hingis ... which got tennis fans excited.

A back injury forced Federer out of the French Open, the first time since 1999 that he had missed a grand slam.

Federer's physical troubles in 2016 began when he injured his knee while running a bath for his twin daughters the day after losing to Novak Djokovic in the Australian Open semifinals. He had surgery for the first time in his career.

He planned on returning at the Miami Open but then had to skip the event because of a stomach illness.

Federer's major rival in his career, Rafael Nadal, has also struggled physically. He shut down his season last month to rehabilitate from a wrist injury.

Federer attended the launch of Nadal's academy in Mallorca last month.

While Federer dropped outside the top 10 Monday, Andy Murray replaced Djokovic as the world No. 1.

Federer and Nadal have been replaced at the top of the game by Djokovic, right, and Murray, left. Djokovic won the first two majors this year, while Murray won Wimbledon and the Olympics.
