Wimbledon fitness fear for defeated Jo-Wilfried Tsonga

Tsonga on his finger injury: 'I think it's serious' (PA)

With Andy Murray, Andy Roddick and Lleyton Hewitt out of the tournament by the end of the second round, organisers of the Aegon Championships here might have thought things could not get any worse. If that was the case they were reckoning without the little finger on Jo-Wilfried Tsonga's racket hand.

Tsonga, the last big attraction in the field, was already struggling against Croatia's Ivan Dodig when he injured his finger in a fall. "I think it's serious," Tsonga said after going on to lose 7-6, 3-6, 7-6 to the world No 69. "I haven't had it examined yet, but it sounds very bad. I felt like I broke something or I stretched a lot of ligaments.

The world No 5 said he did not know whether he would be fit to play at Wimbledon, which begins in 10 days' time. Even before the injury he had looked sluggish against Dodig, who will meet Sam Querrey, the champion here two years ago, in today's quarter-finals.

Nicolas Mahut, who knocked out Murray in the second round, was beaten 7-6, 6-4 by 21-year-old Grigor Dimitrov. The 21-year-old Bulgarian now faces South Africa's Kevin Anderson, who beat Spain's Feliciano Lopez 7-6, 7-6 in a battle between two of the game's biggest servers.

The doubles defeat of Jamie Murray and Marcos Baghdatis to the experienced Indians Mahesh Bhupathi and Rohan Bopanna left Colin Fleming and Ross Hutchins as the only British representatives in the tournament following their 6-2, 6-2 victory over Belgium's Steve Darcis and Olivier Rochus.

Heather Watson's run in the Aegon Classic at Edgbaston ended when she was beaten 6-3, 4-6, 6-1 by Italy's Roberta Vinci. Meanwhile Wimbledon announced that the 20-year-old from Guernsey would take her place in the main draw thanks to her ranking – rather than through a wild card – following the withdrawal of Kaia Kanepi through injury.
