Suns forward Shawn Marion sat out most of the team's workout Sunday with back spasms, putting his availability for Tuesday?s season opener in Los Angeles in question.

?It?s sore, no doubt,? said Marion, who took a few jumpers to begin practice before feeling pain during a one-on-one drill and taking a seat. ?I?m getting treatment (Sunday) and some more before practice (today) and hopefully I?ll be good to go.

?I don?t want to sit out. If I?m decent, I?ll go.?
