London: Novak Djokovic's dramatic fight to keep his Wimbledon title defence alive against South Africa's Kevin Anderson was halted by fading light on Monday.

Djokovic, in danger of becoming the first top seed since Pete Sampras in 2001 to lose in the last 16, had recovered from two sets down to level the fourth round tie at 6-7 (6/8), 6-7 (6/8), 6-1, 6-4 when play was suspended on Court One.
