Serena Williams retired with a left knee injury while trailing 6-4 to Anna Chakvetadze at the Sony Ericsson Championships. The 26-year-old American, who won the event in 2001, hopes that she will be able to continue to compete in Madrid.
"Before the match I had taping for prevention since I was feeling a little tight in both knees. I thought I was tighter in the right knee but then, once I had to increase my range of movement, the left knee got worse," said world No.5 Williams.
"I've had issues with my knees before especially the left knee since that's the one I had surgery on in 2003. It's unfortunate it's happened now and I can't stress how disappointed I am.
"Right now it's swollen and I'm going off to have an MRI at the hospital to see exactly what the problem is. It is my intention to play on in this event."
I’m still waiting for the news whether Serena will continue to play in Madrid. If not, France’s Marion Bartoli will step in. (source: Reuters, photo via Getty Images)
