Suns center Jermaine O'Neal was not at practice Tuesday and will not travel with his team to Sacramento for a Wednesday game against the Kings following an argument with GM Lance Blanks on Monday, according to multiple reports.

The exchange occurred one day after Blanks tapped player development coordinator Lindsey Hunter as interim coach following the dismissal of Alvin Gentry on Friday.

Yahoo! Sports reports details of the exchange between O'Neal and Blanks.

Phoenix Suns center Jermaine O'Neal and general manager Lance Blanks engaged in a blistering, expletive-laced confrontation in the coach's office on Monday, league sources told Yahoo! Sports.

"It was really bad," one Suns source said Tuesday afternoon.

The confrontation happened after interim coach Lindsey Hunter's first practice and unfolded within earshot of several Suns players in the locker room, sources said. It was immediately unclear what precipitated the disagreement, sources said, but there has been considerable unrest within the organization.

CBSSports.com reported that the coaching change was at the center of the exchange.

Veteran Jermaine O'Nealand general manager Lance Blanks were involved in a heated, expletive-filled argument after interim coach Lindsey Hunter's first practice Monday, league sources confirmed to CBSSports.com. One person familiar with the tirade called it a "clearing of the air," but there are many issues remaining for the Suns to clear up before Hunter makes his coaching debut Wednesday night in Sacramento.
