Djokovic is only interested in tennis' biggest prizes. He still has the game to win them, but at age 37 his body is letting him down

Novak Djokovic is 37 and was forced to stop playing because of an injury at two of the past four Grand Slam tournaments.

But, regardless of how you feel about him or what you think about him bowing out, nobody — not even Novak Djokovic — deserves to be booed for being injured. You don’t have to like him. You can absolutely root against him. You can boo him when he’s healthy.
