PARIS (AP) Fabio Fognini has withdrawn from the French Open because of a pulled muscle in his left leg, putting Novak Djokovic into the semifinals.

Fognini says ``the doctors say if I play tomorrow maybe it can be dangerous.''

Fognini beat Albert Montanes of Spain 4-6, 6-4, 3-6, 6-3, 11-9 Sunday to reach his first Grand Slam quarterfinal.

While trailing late in his match Sunday, Fognini winced in pain at the baseline after hitting a serve and clutched at his left leg. He had his leg massaged and resumed, but eventually had his troublesome thigh wrapped in a bandage.

Djokovic is 41-0 in 2011 and has won 43 straight matches, but he will not be credited with a victory over Fognini because the Italian withdrew.
