Wimbledon, England (AHN) - A painful calf strain left Serena Williams wincing on the ground for several minutes during Monday's Wimbledon match versus Daniela Hantuchova.

Although Williams had both legs wrapped and went on to topple Hantuchova 6-2, 6-7 (2), 6-2, the injury put the rest of her tournament in doubt, including Thursday's quarterfinal match against top ranked Justine Henin, who she's had trouble defeating even when healthy.

Williams' family is torn over whether she should continue, as Williams' father, Richard and mother, Oracene Price, lean toward wanting her to quit Wimbledon. Serena's sister, Venus, urged her to continue.

"She got through," said her mother/coach, Oracene Price told AP. "Can she go through another one? You don't know what the pain's going to be like next time."

The lure of taking on Henin, who is attempting to complete the career grand slam, may be too much for Serena Williams to resist. The pair met at the French Open, where Henin won a quarterfinal showdown then two more matches before capturing her fourth Roland Garros title. Serena wants to return the favor in the quarterfinals at the All England Club.

Williams is ahead 6-4 in lifetime meetings, including a match earlier this year at a Miami event. Four years ago in Paris, the pair had a war of words in a match that ended in a Henin victory.

Henin insists the two are on pretty good terms now and keep their battles reserved for volleys. Henin uses a variety of shots and styles to excel, while Serena Williams is more well-known for her powerful stroke and attacking style of play.

Serena Williams may be hampered by her calf injury, which could give Henin a major advantage on Thursday. She also has to decide whether to play tonight's doubles match with her sister. Serena and Venus are two-time doubles champions at Wimbledon.

The Williams' sisters are slated to take on the tandem of Anabel Medina Garrigues and Virginia Ruano Pascual.
