<p>Clijsters, the current US Open and Australian Open champion, issued a statement through the referees office saying she had injured her foot at the Den Bosch Open on Tuesday. <br /><br />"I'm very, very disappointed to have to withdraw from Wimbledon after injuring my foot again at the tournament in Hertogenbosch," said Clijsters, who was the second seed. <br />"At this moment I feel frustrated that it has to happen now before one of my favourite tournaments. <br /><br />"I've always enjoyed being a part of the Wimbledon atmosphere but I have no other choice now but to rest, recover and to not play tennis for a few weeks." <br /><br />The Belgian's withdrawal means last year's runner-up Vera Zvonareva from Russia becomes the second seed having originally been seeded three. <br /><br />The popular Clijsters, who won the 2009 US Open just three tournaments into a comeback from a two-year retirement in which she gave birth to a daughter, has had her season disrupted by injury since beating China's Li Na to win the Australian Open. <br /><br />She injured her ankle while dancing at her cousin's wedding, resulting in a two-month lay-off, and although she returned to play in the French Open she struggled and was knocked out in the second round by Dutch world number 114 Arantxa Rus. <br /><br />Serena Williams, the reigning Wimbledon champion who has just returned from an 11-month absence because of injury and health problems, rises to number seven seed. <br />The seeding committee had earlier bumped up the American from her world ranking of 26 to take into acccount her formidable record at the All England Club. <br /><br />With Clijsters out, Williams' chances of a stunning comeback to claim a fifth Wimbledon singles title will be enhanced as will the prospects of sister Venus, who is 23rd seed, after her return from a five-month injury break in Eastbourne this week. <br /><br />Last year's beaten Wimbledon semifinalist, Tsvetana Pironkova of Bulgaria, is seeded 32, meaning she will avoid any of the big names until the third round.<br /><br />Querrey pulls out<br /><br />American Sam Querrey has withdrawn from an arm injury. The big-serving Californian complained of arm pain at Queen's Club last week where he was surprisingly beaten by British wildcard James Ward. <br /><br />Querrey, ranked 40 in the world, won the Queen's tournament last year and went on to reach the fourth round at Wimbledon where he lost to Britain's Andy Murray. <br /><br />The American number three's place in the draw will go to a lucky loser from the qualifying tournament.</p>
