The Australian NBA star Andrew Bogut has been ruled out of Milwaukee's next three matches due to lingering back spasms.
The 215 centimetre centre, who only returned to action a week ago after missing four games, will now miss the Bucks three-game road trip to Sacramento, the Los Angeles Clippers and Portland.
Bogut says it gets scary when sometimes you're just lying down and you start getting pain without even doing anything.
His earliest return would be next Wednesday when the Bucks play host to Dallas.
