The clock is ticking for Novak Djokovic and what appears to be a groin or hamstring strain after his quarter-final victory at Melbourne Park, after he expressed fears the injury could hinder his pursuit of an 11th Australian Open and 25th grand slam title.
Djokovic overpowered Carlos Alcaraz in four sets in a match that finished close to 1am Wednesday in Melbourne, fighting back after losing a first set in which he also received medical treatment on his upper thigh.
