Novak Djokovic described his shock third-round elimination from the Rome Open by outsider Alejandro Tabilo on Sunday as “concerning”, two days after he was hit on the head by a bottle which he said has caused nausea and dizzy spells. 

Djokovic’s bid for a record-extending 41st Masters 1000 title was ended in just over an hour by Chilean Tabilo, who is ranked 32nd in the world and claimed his first win over a Top 10 opponent, 6-2, 6-3.
