I saw his long interview at the Genesis tournament site. He was visibly upset/sad.
He was going to check on the healing process on his back in a couple of days with an MRI.
I thought he felt like that was not going well.
He is not a happy man...
He looked like he was on pain meds for his recent back surgery, we'll never know, to toxicology will be done. This was really a big mistake on his part, in tennis they call it an unforced error and this will effectively end his career. He may play again, but not another major and likely not even another tournament win.
He doesn't want to retire, but he's got to realize he can't be the young Tiger forever. He's shown everyone what he can do but his body is telling him it's time to put the clubs in the closet and find another way to be happy. Now he'll a long time to think it over. I wish him a good future.
