Well, exercise injury is an entire field of study, and hence the existence of the profession of physiotherapy. Yoga is just one more way you can hurt yourself and need a physiotherapist.
There was a great comment on the NYTimes article by someone called Stevi that I would like to quote here, "Yoga doesn't wreck the body. People wreck their bodies by practicing yoga with a lack of awareness and by taking classes from instructors who don't have enough experience. Yoga is an ancient discipline--a tool for self-realization. It's unfair to hold yoga responsible for our misuse of it. Yoga involves an eight-fold path of which asana is only one tenant. If you are practicing asana without without the other aspects of yoga such as ahimsa (non-harm), santosha (contentment), aparigraha (non-greed), etc., then you are destined for problems. Find a good teacher, and yoga is the greatest gift."
