Novak Djokovic reckons the 14-day quarantine prior to the Australian Open is the cause of the increased number of injuries.
The Serbian top seed has overcome some knocks of his own so far in Melbourne, and beat Alexander Zverev on Tuesday to reach the last four.
Djokovic rallied from a set down to beat Zverev in four, winning 6-7, 6-2, 6-4, 7-6 on an empty Rod Laver Arena.
And, after being quizzed by Jim Courier on court, he gave some of his thoughts on the increased amount of injuries this fortnight. (Eurosport, 1:45pm)
“Tough luck for Grigor (Dimitrov) today,” the world number one said.
“I thought he was playing better for a set and a half and, again, an injury as well.
“There’s too many injuries, you know. I mean, honestly, I’m just hoping this is all temporary so we can go back to what we’re used to.
“The 14 day quarantine, people don’t realise but I think the amount of injuries in this tournament has shown how much of an effect it has on players’ bodies.
“It’s taking its toll unfortunately for all of us.”
Novak Djokovic has had injury troubles during the Australian Open
Dimitrov lost in four sets to Aslan Karatsev earlier in the day, after injuring his back during the third set.
Yesterday, Matteo Berrettini pulled out of his clash against Stefanos Tsitsipas, while Casper Ruud retired against Andrey Rublev.
Zverev himself has had issues while Johanna Konta retired in her first match a week ago.
Perhaps increased risk of injuries is the price players have had to pay for being allowed to play the Australian Open, and earn prize money as a result.
With COVID-19 taken so seriously in Australia, it is hard to imagine a perfect scenario that appeased everyone.
