The Milwaukee Bucks were without starting center Andrew Bogut for their preseason opener on Monday night due to a migraine, the Milwaukee Journal-Sentinel is reporting.

Bogut, who was back at practice on Tuesday and is expected to play against Detroit tonight, said the migraines are completely random and can come on at any time.

I could get two in a week or I could get two in a year; it?s that random,? Bogut said of the severe headaches. ?I haven?t had one for about six months. Sometimes I think a little bit of stress brings it on. Doctors say to avoid cheese, caffeine, coffee, soda. By the end of the list, you can?t eat or drink anything.?

Bogut said he thought the headaches might stem from a childhood incident, when he rammed his head on the top of a picket fence.

?When I was about 11, I still remember it to this day,? Bogut said. ?I cut myself open on a fence. I?ve gotten them ever since then. I was playing (Australian rules) football outside and bent over to pick up the football, and it was getting dark, and I smacked my head right on it.?
