Matias Fernandez's stunning free kick saw Champions League-chasing Fiorentina snatch a 2-2 draw at Parma in a thrilling Serie A match which also featured three red cards on Monday.

Fiorentina remained six points behind third-place Napoli after an equally magnificent free kick from on-loan Napoli forward Emanuele Calaio rescued a 1-1 draw for Genoa against his parent club.

Decorated Jamaican sprinter Veronica Campbell-Brown said she has been cleared to return to the track by an international panel.

Barcelona paid 13.55 million euros ($18.6 million) to Spanish tax authorities on Monday to cover any potential irregularities in its signing of Neymar, all the while maintaining its innocence of the fraud charges levied against it.

The Spanish champion said in a statement it had paid the "complimentary" amount to cover any "eventual interpretations that could come out of the contracts signed relating to the transfer of Neymar. Meanwhile we are convinced of the legality of our initial fulfillment relating to our tax obligations."

By the busload, the world's athletes and visitors rolled toward Sochi's airport and took off for home Monday, fresh from a Winter Games experience that many Russians pronounced a smashing success and that the Olympic movement's chief enthusiastically labeled a victory for the region and the host nation. "Yes! We did it!" one Olympic volunteer exulted as she darted into the night.

After 17 days of global sport and spotlight, Sochi ended the spirited chants of "Ro-ssi-ya! Ro-ssi-ya!" and started cleaning up.

The Los Angeles Clippers showed they are a strong contender for the NBA Western Conference title by winning 125-117 at Conference leader Oklahoma City on Sunday, with Jamal Crawford scoring 36 points.

The result moved the Clippers 3 games clear atop the Pacific Division, while the Thunder's lead in the Northwest was trimmed to four-and-a-half games ahead of Portland, which staged a creditable comeback win over Minnesota despite being without leading scorer LaMarcus Aldridge.

Dale Earnhardt Jr. won a rain-delayed Daytona 500 on Sunday, a decade after his first victory in the "Great American Race."

Rafael Nadal returned from a troublesome back injury to win the Rio Open on Sunday, defeating Alexandr Dolgopolov of Ukraine 6-3, 7-6 (3).

Atletico Madrid slumped to a stunning 3-0 loss at Osasuna on Sunday, leaving Real Madrid as the sole leader of the Spanish league for the first time since May 2012.

Russia guaranteed top spot in the Sochi Olympics medals table on Sunday after a clean sweep of the podium in the men's 50km cross country race.

Smoothly run and sometimes dazzling, the Sochi Olympics fulfilled President Vladimir Putin's promise of a "spectacular event", even if doubts about the sustainability of the infrastructure and the political background were never fully banished.

To make his dream a reality, Putin in half a decade turned largely untouched marshland south of Sochi into an Olympic park with six stadiums and the almost virgin mountains above into a world-class snow resort.
