Right after getting Lionel Messi back from injury, Barcelona lost Neymar for three-to-four weeks because of a right ankle sprain.

The Brazil striker was hurt in Thursday's 2-0 Copa del Rey victory at Getafe while attempting to extend his dribble in the 22nd minute, falling under his own weight without any contact from an opposing player.

Manchester United manager David Moyes announced that Wayne Rooney will miss Sunday's Premier League match against Chelsea because of injury.

Formula One legend Michael Schumacher remains in a stable condition after his December 29 skiing accident, his spokeswoman said Friday, after a wave of speculative reports that he may never recover.

Lionel Messi scored a pair against Getafe to power Barcelona into the Copa del Rey quarterfinals with a 2-0 win which was mired by an injury to Neymar on Thursday.

Li Na had one simple request before answering questions in her on-court, post-match interview after battling for two-and-a-half hours in the brutal heat at the Australian Open on Friday: "Can we stand in the shadow?"

Jose Sulaiman, the longtime head of the World Boxing Council who promoted renowned fighters and introduced rules to protect boxers, died Thursday. He was 82.

Sulaiman's son, Mauricio Sulaiman, said the man who many say raised the profile of the sport in his four-decade leadership at the Mexico-based council died at a hospital in Los Angeles.

Pirelli secured a new three-year contract with motor sport's governing body on Thursday to remain Formula One's sole tire supplier, a welcome relief for the Italian manufacturer following an extremely difficult season.
