Wimbledon finalist Agnieszka Radwanska canceled a news conference Friday because of a respiratory illness that made it difficult for her to speak.

Radwanska is scheduled to meet four-time Wimbledon champion Serena Williams for the title Saturday.

"Unfortunately I have picked up an upper respiratory illness, which is affecting my nose and throat," Radwanska said in a statement. "I have been playing a lot of matches here in the rain and cold wind, and I haven't been well for a few days. The most important thing is that I'm feeling good on the court and playing some good tennis, despite not being able to talk much away from the court."

Radwanska played with the ailment Thursday, when she beat Angelique Kerber 6-3, 6-4 and became the first Polish player to reach a Grand Slam final since 1939. Her news conference after the match was cut short when she had a coughing fit, and her media session Friday was canceled shortly before it was scheduled to begin.

"I can't speak for very long, and so I have done as much as I can do today," Radwanska said in the statement released later. "I will do whatever it takes to make sure I'm ready to play the best I can."

Radwanska pulled out of women's doubles shortly before a match Wednesday because of the illness.
