OAKLAND -- Jermaine O'Neal left Thursday night's Game 6 after spraining his right knee on a play that some in the Warriors locker room are calling dirty.

"Either he has terrible balance for a professional athlete or he was diving for my legs," O'Neal said of the Los Angeles Clippers' Glen Davis.

X-rays were negative, but O'Neal said he'll have an MRI on Friday. The injury occurred when Davis lowered his shoulder into O'Neal's knee with 9:39 left in the second quarter. O'Neal didn't return after the foul call.

The play angered some of O'Neal's teammates, including Marrese Speights. He picked up a technical foul just 2½ minutes later for taunting Chris Paul after he fouled the Clippers point guard.

"I was upset because I saw what happened. It was a dirty play," Speights said.

Warriors coach Mark Jackson said he wasn't sure if the play was clean or not.

"I didn't get another look at it so I'm not sure," he said. "I'm sure the league, which does an outstanding job of monitoring plays like that, will take a look at it and make decisions."

O'Neal's injury adds to the Warriors' health problems at center, where Andrew Bogut is still out with a broken rib and Festus Ezeli hasn't played all season as he recovers from knee surgery. O'Neal's status for Saturday's Game 7 in Los Angeles is unknown.

"We'll see how he feels moving forward," Jackson said.

The Warriors have played the past three games with a small starting lineup featuring David Lee at center and Draymond Green at power forward, but O'Neal's injury takes away a valuable big body off the bench.

Bogut still isn't healthy enough to watch games from the bench, so his return is not imminent. But could Ezeli make his season debut in Game 7.

"It's coming," Ezeli said of his possible return. "I've just got to keep working, and it's going to come. It's going to come soon. ... I've been mentally preparing. It's just kind of worked out that rehab is longer than expected, but I'm staying positive, I'm staying focused. When the time comes, I'll be ready."

  • The victory snapped a streak of seven straight losses in elimination games for the Warriors, dating to 1987.

    That's when Eric "Sleepy" Floyd scored an NBA record 39 second-half points and 29 fourth-quarter points in a 129-121 victory to beat the Los Angeles Lakers in Game 4 of the Western Conference semifinals. The Lakers closed out the series in Game 5.

    This series marks the first time the Warriors have played in a Game 7 since 1977.

  • The New York Post and ESPN reported banned Clippers owner Donald Sterling, 80, is battling prostate cancer. Clippers coach Doc Rivers had little to say on the subject except he hopes it isn't true.
