Djokovic unsure about injury return after 22nd Tennis Grand Slam

After his record-equalling 10th Australian Open win, Novak Djokovic says he hopes to return to action shortly but remains unsure about how quickly his injured hamstring will heal.

His 6-3, 7-6 (7/4), 7-6 (7/5) victory over Stefanos Tsitsipas saw Djokovic equal Rafael Nadal's men's record of 22 Grand Slam tournament wins and go back to world number one in the rankings.
