World No. 8 Richard Gasquet has withdrawn from next month's ATP Adelaide International with an injury, making Australian Lleyton Hewitt the tournament's top seed, organisers said on Thursday.
The Frenchman has a knee injury, which has forced him to delay the start of his 2008 season.
Tournament co-director Peter Johnston said Gasquet has decided he will still come to Adelaide in the lead-up to the tournament for media opportunities.
The withdrawal enables former Wimbledon and US Open champion Hewitt to take over the top seeding for the 465,000 dollar tournament.
It also means another Frenchman, former Adelaide finalist Michael Llodra, moves into the main draw.
Llodra was a runner-up in Adelaide in 2004 and is a two-time Australian Open (2003, 2004) doubles champion.
The Adelaide International takes place at the Memorial Drive courts from December 31 to January 6.
