A friend of mine injured his hip about the other year and it took him about two months (with one setback when he got tired of waiting) to be able to run without pain. I'm not sure what Robby's hip issue might be, but a hip injury would probably have an impact on every aspect of his game so he should take his time and make sure he's fully recovered before he returns to tournament play.
I agree with you 100%. Most players try to come back too quickly and like your friend all that gets them is a setback. Robby could always use this time to try to get his head back together
When he isn't physically injuried it seems like Robby's main problem on tour is between his ears
