Lance refiles his USADA lawsuit

CYCLING: Lance Armstrong has refiled his lawsuit against the United States Anti-Doping Agency as he continued to contest charges he used drugs to help him win his record seven Tour de France titles.

The 40-year-old initially filed a lawsuit in a US federal court on Monday which was dismissed by a judge as being a "lengthy and bitter polemic", designed to attract media attention and public sympathy.

Armstrong and his lawyers were given 20 days to refile his suit against USADA and the body's chief executive, Travis Tygart, which they have now done.

The suit asks the US District Court in Armstrong's hometown of Austin, Texas, to find that USADA "does not have the right to charge and sanction him and strip him of his titles".

USADA has given Armstrong a deadline of Saturday to enter into arbitration to contest the charges, or accept sanctions which include removing his seven Tour titles and imposing a lifetime ban.

That ban would also cover triathlon, the sport in which Armstrong now competes.

Haye's driven by 'hate' for Chisora

BOXING: Adam Booth insists David Haye is in frightening condition as he prepares to meet an opponent he "hates".

Haye faces British rival Dereck Chisora at Upton Park on Saturday night in a heavyweight showdown mired in controversy.

The rivals brawled at a press conference after Chisora's WBC title loss to Vitali Klitschko in February. Haye's dislike for Chisora is genuine, according to his trainer Booth.

"This is personal. This is way more personal than the Wladimir Klitschko fight. That was business, but he hates Dereck Chisora," Booth said.

"David's in frightening shape and that's testament to the training he's done."

Siofra scorches into World Junior semis

ATHLETICS: Distance runner Siofra Cléirigh-Buttner proved her versatility and massive promise when she was Ireland's best performer on the first day of the World Junior (U20) Championships in Barcelona.

Raheny's Kevin Dooney finished 24th of 34 in the 10,000m final, clocking 31:56 in a race won in 28:16, with African runners taking the first five places.
