The training rooms for Olympic badminton participants have been poor in Rio, and Danish player Viktor Axelsen got the worst of it.

"When I was in the training hall and came down around the corner [the floor fell apart under me] and I fell into a hole that was approximately 10-15 centimeters deep," he said to Fyens.dk, via a translation. "[I'm] just happy that [nothing more happened]."

Henrik Fallesen of Badminton Magazine said the following of the practice courts: "There have been problems with the floor [in] the hall. It was too rough and soft, so the organizers had to change since Monday. Training courses were also uneven, so the players had a real risk of tripping. Hopefully it's been resolved now."

Fortunately, the hole wasn't deep enough to cause injury, but it sounds like the badminton players are in desperate need of an improved practice facility.
