Leander Paes and Lukas Dlouhy advanced to the semi-finals of the doubles event of the ATP Brisbane International after getting a walk over from the local pair of Ashley Fisher and Stephen Huss on Thursday.

A knee injury to Fisher forced the home favourites to opt out of the quarter-final contest against the top seeded Indo-Czech pair.

Paes and Dlouhy will now fight it out with Jurgen Melzer and Philipp Petzschner, who shocked third seeded Michael Llodra and Andy Ram in their last-eight pair match of the $372,500 hard court event.

The unseeded Austrian-German pair scored a 5-7, 6-2, 10-8 win over the French-Israeli combination.

Paes, who gave a miss to ATP Chennai Open to prepare well for the Australian Open, and Dlouhy had beaten Australian Ball Carsten and American Sam Querry 7-5, 6-3 in the first round.
