Q. (No microphone.)
COLLIN MORIKAWA: Muscle in the back, lower back, just kind of gave out. We were doing some like reflex stuff, trying to reach down and try to pick something up like quick and low. Went after it weird. Literally have never had this in my life. I've hurt may back briefly before, but like nothing has been this bad, especially never warming up, never doing anything pre-round. It sucks. I think it's the first tournament I've ever withdrawn from in my entire life. I can't really think of anywhere else that I have had to withdraw. It sucks because this is a tournament that I love. I've played well and put ourselves in contention. But I have to look out for myself and got to be smart. We still have a handful of tournaments left before playoffs. Obviously the U.S. Open and the British Open in two weeks time is going to be plenty enough for me to get ready. But just bad, bad time.
Q. Where was maybe the other time had you a back injury?
COLLIN MORIKAWA: Yeah, I hurt myself in college. I was out for like a week. (Wind noise) I pulled a muscle in my left side and (wind noise). But this was just, I mean I crashed to the ground, just random spasm. Like it wasn't lingering, it wasn't going through my body. It was just a spasm in my back. Literally tried to hit 10 balls. Hit my 9-iron. Chunked 9-iron about 95 yards. So I don't think that's playing out here at Muirfield Village.
Q. What do you think the process will be, the next steps will be in the next day or two?
COLLIN MORIKAWA: Just recover, get some work done. That's all I can do. Like I'm not, I'm not too worried about it. I mean, I do want to be a hundred percent by the time, you know, end of next week, so I can get some really good work in. Just not a time in the season where you want it to happen. And all signs, I woke up fine, all signs led to me being fine. Just freak little accident warming up. Never doing that exercise again.
Q. So there was nothing you did, it was just that one exercise?
COLLIN MORIKAWA: Not a single thing. Just, when you reach a little too low and you reach too fast, stuff like that happens. Unfortunately, it just happened at the wrong time.
