INDIANAPOLIS — Jim O'Brien's future as Pacers coach was in question heading into a four-game road trip, and team president Larry Bird didn't get the answers he wanted.

Bird fired O'Brien on Sunday after the team squandered a promising start to the season by losing seven of its past eight games.

Bird had discussed the team's coaching options with owner Herb Simon, saying he wanted to see how the team performed on a Western swing against the Los Angeles Clippers, Golden State, Portland and Denver.

"We were in three of the games and the Denver game we didn't really have a chance," Bird said.

The Pacers returned to Indiana to play the Orlando Magic on Wednesday, with O'Brien's status tenuous. Orlando won 111-96 win, and Bird had seen enough.

"We came home to Orlando, and really, the game was over in the first three minutes," Bird said. "So that's when I really started thinking that we really probably needed to do something. I called Mr. Simon up and he said, 'whatever you want to do' and so, here we are."

The Pacers went 121-169 under O'Brien in a 31/2; seasons and are 17-27 this season. O'Brien was ejected in his final game, a 110-89 loss to Chicago on Saturday.

Assistant coach Frank Vogel will take over for the rest of the season. He has been a scout for the Los Angeles Lakers and Washington Wizards, and served as an assistant coach for O'Brien in Philadelphia and Boston.
