Former champion Lindsay Davenport has hinted that she might have played her last Wimbledon after pulling out of this year's event with a knee problem.

The 1999 champion was due to play Gisela Dulko in the second round on Thursday, but withdrew hours before with the ongoing injury.

Davenport told BBC Sport: "I would be surprised if I was back here playing.

"I am looking forward to the Olympics and playing the US Open. After that there are not a lot of plans."

On Tuesday, in her first match at Wimbledon since 2005, Davenport hobbled past Renata Voracova 6-3 5-7 6-3.

The 32-year-old had been idle for two months after sitting out the clay-court season. She withdrew from the warm-up tournament at Eastbourne last week.

"After my match I went to the hospital for an MRI scan which came out looking good but it showed I had inflammation behind the knee cap.

"At first that was a major relief and no immediate danger, but it was just really inflamed and painful," she said.

"I rested all day on Wednesday and wanted to see how I was but after a warm-up I felt 20-30 % which is not good enough - so it's prescribed rest.

"It's not an easy decision to make but in the second round I want to be 100% and have a chance to win and not just hope to get through another set or another round.

"I worked hard to get back here but it's just the way it goes.

"The diagnosis is three to four weeks I should be fine. I was concerned about the Olympics 48 hours ago but the doctors are confident."

Dulko receives a walkover into the last 16 where she will play Russia's Elena Dementieva.
