Why is Master program closing down in US? To pursue Masters will be best option?

Hello friends,
I have just given my final year exams for bachelors of physiotherapy and i intend to study further in US. But i have little confusion over Masters program which is closing down in some universities and getting converted into Doctorate program. Now is it fine to do Masters program in US?

Second question is about prospect as Master in Science for Exercise physiology or Sports medicine field. Are they both second best option if masters or doctorate dosent workout?

Looking forward for replies...
