Mahesh Bhupathi and his partner Mark Knowles did not have to do anything to enter the quarterfinals of the $2,615,000 ATP Rogers Masters as they got a walk over from their opponents in the second round.

The fourth seeded Indo-Bahamas were up against American duo of Mardy Fish and Andy Roddick, who conceded the match because of knee injury to Fish.

Bhupathi and Knowles are yet to play a single ball in the tournament as the pair had also got a bye in the first round of the sixth of the 10 Masters Series tournaments.

They may next face seventh seeded Leander Paes and his Czech partner Lukas Dlouhy, if the Indo-Czech combine can manage to prevail over Swiss pair of Roger Federer and Stanislas Wawrinka in their second round match.
