When Steve Nash was a Canadian teenager moving down to California to accept his only university scholarship offer 21 years ago, he never could have imagined his remarkable NBA career would lead to the dubious honor he's getting this fall.

The Los Angeles Lakers' 39-year-old point guard is the oldest player in the NBA. And it isn't an achievement that's going on the mantel next to his two NBA Most Valuable Player trophies.

A Jamaican disciplinary panel gave three-time Olympic gold medalist Veronica Campbell-Brown a public warning Wednesday and cleared her to return to competition some five months after she returned a positive doping test on the Caribbean island.

Campbell-Brown, one of the cornerstones of Jamaica's recent sprinting success, returned a positive test for a banned diuretic at the Jamaica International Invitational meet in May. She was suspended from competition while the disciplinary committee reviewed the case and missed Jamaica's national championships to try and qualify for this summer's worlds in Moscow.

Formula One team Marussia has extended its contract with driver Jules Bianchi through the 2014 season.

Marussia announced Thursday, ahead of this weekend's Korean Grand Prix, that the Frenchman would be retained.

Formula One championship leader Sebastian Vettel is cautious about the prospects of Red Bull continuing its dominance at this weekend's Korean Grand Prix, saying the layout of the circuit does not suit the car's strengths.

Vettel leads Ferrari's Fernando Alonso in the drivers' championship by 60 points with six races remaining, and while that margin could shrink with a couple of bad races, the dominant nature of the German's victories in the past three races suggests the remainder of the season will be little more than an extended coronation.

Borussia Dortmund and Chelsea recovered from poor starts in the Champions League by winning their first group matches on Tuesday, while Barcelona beat 10-man Celtic 1-0 to avoid a second consecutive loss at Celtic Park.

Robert Lewandowski scored a brace as Dortmund, last-season's runner-up, defeated Marseille 3-0 in Group F. Arsenal leads the group with six points after a 2-0 win over Napoli.

David Nalbandian, the 2002 Wimbledon finalist who caused an uproar a decade later by injuring a line judge at another tournament, retired from professional tennis Tuesday because of a shoulder injury.

The 31-year-old Argentine player described it as a "difficult day," but told a news conference that he was "super grateful" to his sport.

Surrounded by stewards and facing the wrath of a three-deep line of seething home fans, Neymar was being escorted out of Celtic Park just as Neil Lennon launched his criticism of the Barcelona winger.

"I don't think Neymar does himself any favors by the way he behaves at times," the Celtic manager said. "Our supporters are very respectful of great players. (Barcelona playmaker Andres) Iniesta walks off tonight to a standing ovation from the Celtic support. While Neymar, he gets booed every time he touches the ball."

Pau Gasol politely stepped out of the paint when Andrew Bynum emerged as a dominant NBA center for the Los Angeles Lakers. The seven-foot-Spaniard stayed in a complementary role when Dwight Howard joined the club for one crazy season.

With Bynum in Cleveland and Howard now in Houston, Gasol is eager to be the Lakers' man in the middle again.

Almost exactly a year after a routine pre-training camp physical uncovered a heart condition that threatened his career, and maybe worse, Channing Frye is back with the Phoenix Suns.

Suns officials say they decided over the weekend that Frye should re-join the team after he was unanimously cleared by several doctors.

Romelu Lukaku scored twice and set up the other goal to lead Everton to a 3-2 win over Newcastle on Monday, lifting the Premier League's only unbeaten team to fourth in the standings.

The Belgium striker, who is on loan from Chelsea, shredded Newcastle's flaky defense to score either side of a well-taken effort by exciting youngster Ross Barkley, giving Everton a 3-0 lead after 37 minutes.
