TABLE TENNIS - European Olympic Qualification Tournament, Luxembourg (11-15 April); Paul Drinkhall leads a six-strong Great Britain team in Luxembourg.

LAST WEEK'S HIGHLIGHTS
GB track cyclists strike gold in Australia; Ben Ainslie enjoys comeback win; Louis Smith clinches silver in China; and GB name three NBA stars in their Olympic squad.
Great Britain won six gold medals - five in Olympic events - at a highly successful Track Cycling World Championships in Melbourne.
Among many highlights, Sir Chris Hoy won his 11th world title with a phenomenal last-ditch move in the men's keirin. That made up for his 2-0 defeat to GB team-mate Jason Kenny in the individual sprint, a result that has left the British selectors with an Olympic headache.
Teenager Laura Trott, whose family live within sight of the Olympic Park in London, won the women's omnium and also teamed up with Dani King and Jo Rowsell to win the women's team pursuit.
And Victoria Pendleton provided another highlight when she overcame her Australian rival Anna Meares on her way to gold in the women's sprint. Meares, like Chris Hoy, recovered well by winning the keirin.
Hosts Australia topped the medal table; like Britain they won six gold medals but also won six silver medals to Britain's four.
Britain's three-time Olympic champion Ben Ainslie won gold in the Finn class at the Palma World Cup regatta.
It was Ainslie's first competition win since being disqualified for gross misconduct at the World Championships in December.
And there was a silver for Olympic champion Paul Goodison in the Laser class behind Simon Grotelueschen of Germany.
Louis Smith overcame a fractured finger to win a silver medal on the pommel horse at the World Cup in China.
The 22-year-old tried a new routine in the final, scoring an impressive 15.600 points, but was beaten by Hungary's Krisztian Berki, with 15.750 points.
Smith, who won bronze on the pommel horse in Beijing 2008, had scored 15.825 points in qualification.
Smith had been a doubt for the event after stubbing and breaking his finger on the high bar days before the start.
British cyclist Nicole Cooke has won the fifth and final stage of the Energiewacht Tour in the Netherlands.
The Faren-Honda Racing Team rider claimed victory in the 89-mile stage for her first major victory this year.
The win means Cooke, 28, finished 59th overall in the event, which was won by Germany's Ina Teutenberg.
The reigning Olympic champion faces a battle with Lizzie Armitstead to lead the GB team at the 2012 Games.
NBA players Ben Gordon, Byron Mullens and Luol Deng have been included in Great Britain's provisional men's basketball squad for the Olympics.
US-raised Gordon and Ohio-born Mullens, who play for the Detroit Pistons and the Charlotte Bobcats respectively, are available for the first time.
Chicago Bulls forward Deng is also included in the 21-man squad.
Coach Chris Finch will reduce the group to 16 in May and then make a final cut to 12 at the start of July.
Great Britain's men lost all three of their matches in the Pinsent Masons' London Handball Cup at Crystal Palace National Sports Centre.
Playing in the round-robin tournament with Argentina, South Korea and Tunisia, the hosts opened with a heavy 32-15 defeat against the South American side.
They then suffered an even heavier 41-15 loss to Tunisia, who went on to win the tournament.
But Dragan Djukic's side did at least restore some pride against South Korea in their final game, Steven Larsson scoring 14 goals in a narrow 29-25 defeat.
