No wonder we need rehab now ???????? @rafaelnadal ???? @espn

Novak Djokovic may still be out with an elbow injury, but he's not down. The Serbian still has some jokes left—referring to his classic 2012 Australian Open final that left both players struggling to remain upright during the awards ceremony. 

"No wonder we need rehab now," Djokovic said, tagging Nadal. 

That year in Melbourne, Djokovic outlasted Andy Murray in nearly five hours in the semifinals, before squeezing past Nadal, 5–7, 6–4, 6–2, 6–7 (5), 7–5 in five hours and 53 minutes (the longest final in Grand Slam Open era history). 

Nadal has been struggling with a leg injury but is scheduled to play Acapulco. Djokovic underwent a small medical intervention on his elbow after Melbourne, but is already back in the swing of things.
