Professional Tennis Players Association says brutal schedule behind Canadian Open withdrawals

In short:

The Professional Tennis Players Association (PTPA) believes a string of withdrawals for this year's Canadian Open is more evidence the tennis season is too long.

Jannik Sinner, Carlos Alcaraz and Novak Djokovic are all out of the men's draw, while Victoria Mboko, Karolina Muchova and Emma Raducanu are among the missing names on the women's side.

Tournament organisers believe recurring late withdrawals from Masters 1000 events have become a wider issue for the sport.
