Jermaine O'Neal knows this could be it, but he didn't want it to end like this.

The Golden State Warriors big man, who may retire after this season, went down in a heap early in the second quarter of his team's 100-99 Game 6 victory Thursday against the Los Angeles Clippers, with even-bigger man Glen Davis curiously barreling him over after O'Neal grabbed a rebound and spraining his right knee. O'Neal was helped off the court, unable to put any weight on the knee.

After sitting out the rest of the night and with an MRI scheduled for Friday morning, he didn't hesitate to call out his former Boston Celtics teammate.

"It's just a dirty play, to be quite honest," O'Neal said. "I mean I'm not going to go try to dive into somebody's legs — it wasn't a scramble for the ball. I respect people's ability to come out and perform and take care of their family based on their bodies.

"Either he has terrible balance as a pro athlete, or that was a dirty play," the six-time NBA All-Star added. "God don't like ugly."
