World number one Novak Djokovic was knocked out of the BNP Paribas Open in the third round by Philipp Kohlschreiber at Indian Wells.
The Serb, who currently holds three of the four Grand Slam titles, was beaten 6-4 6-4 by the German world number 39.
Djokovic broke his racquet in anger after Kohlschreiber - who had lost his past seven matches against the 31-year-old - took the first set.
Kohlschreiber will play French 18th seed Gael Monfils in the fourth round.
The match between Djokovic and Kohlschreiber began on Monday but was delayed until Tuesday because of heavy rain.
