Novak Djokovic sows French Open doubt after knee injury

Novak Djokovic cast doubt over his French Open hopes after admitting he needed anti-inflammatory medication to treat a knee injury as he pulled off another astonishing escape in a five-set victory over Francisco Cerundolo on Monday. The world number one outlasted Argentine 23rd seed Cerundolo 6-1, 5-7, 3-6, 7-5, 6-3 for his record 370th win in a Grand Slam match as he reached a 15th consecutive French Open quarter-final.
