Los Angeles ? Just a few hours before the start of the regular season Tuesday, all was not well in Lakerland.

Coach Phil Jackson fined Kobe Bryant an undisclosed amount for his highly critical comments of teammate Shaquille O’Neal, and the team met for 20 minutes to discuss a rift between two superstars that has escalated into a full-blown feud.

“There were no signs or indications that it would snowball the way it has in a matter of 36 hours, so we’ll see what happens from here,” teammate Derek Fisher said.

Bryant was not in uniform for the opener against the Dallas Mavericks after he said he didn’t think his surgically repaired knee was strong enough to withstand the rigors of a 48-minute game. The Lakers had expected him to play until hearing otherwise Monday on ESPN.

The Lakers put aside their differences and defeated Dallas, 109-93, Tuesday night.

The other thing hurting Bryant was his feelings, and it appears there’s no easy way for the Lakers to soothe them.

Bryant castigated O’Neal during a telephone interview with ESPN, calling him “childlike,” “unprofessional,” “selfish,” “fat” and “jealous.” He also accused the 7-footer of overstating the severity of his foot injury last season when he reported to training camp overweight.

Bryant’s comments came a day after O’Neal said the Lakers were “my team,” adding that Bryant needed to be more of a team player — an observation based on two exhibition games.

At practice Monday, Jackson ordered the team not to discuss the dust-up with reporters. He fined Bryant for defying that order by talking to ESPN later that day.

“We felt we had an agreement yesterday and he didn’t uphold that,” Jackson said. “I think this is something we’ve asked our players to work out on their own and in private if they have personality conflicts.”

Bryant made an appearance at the end of the third quarter, emerging onto the court after watching the game from the players’ lounge. Bryant received a loud ovation from the sellout crowd at Staples Center when he was shown on the scoreboard, and he began the fourth quarter sitting next to O’Neal on the bench.

The conflict between O’Neal and Bryant has been simmering throughout their seven seasons together, but their public potshots have never been as personal as the most recent ones.

“My thought is to say ‘Kids, cut it out.’ It’s a guy thing. You say this, I say that. You say that, I say this and here we go,” commissioner David Stern told reporters in San Antonio. “Someone has to stop it, because at bottom it distracts us from our league and the teams.”

Adding another layer of tension for the team is the publicity brought by the sexual-assault charges against Bryant.

Bryant lashed out publicly after Jackson declined to get in the middle of the fight.

“He said: Do I want to address it, not calm it down, and I went back to him and said it’s not significant enough to comment on,” Jackson said. “But we did have an exchange, and that’s one thing I will verify.”

One member of the Lakers said Tuesday morning’s meeting lasted about 20 minutes, with O’Neal and Bryant addressing the team but not each other. The only other player to speak was Karl Malone, the player said.

“What we tried to do was not to overkill the situation,” Fisher said. “We all know it’s there, we’re aware of it, it’s not necessarily going to go away just today, so we addressed it.”

Among the bombshells Bryant dropped in his comments about O’Neal was a plan to opt out of his contract at the end of this season and become a free agent — something Bryant said he first discussed with O’Neal out of respect.

“If leaving the Lakers at the end of the season is what I decide, a major reason for that will be Shaq’s childlike selfishness and jealousy,” Bryant said.

Lakers general manager Mitch Kupchak said trading Bryant was not an option being considered.

Players said the rift between O’Neal and Bryant wasn’t surprising — they’ve feuded before. What caught them by surprise was how quickly the feud escalated, coming to a head the day before the season started.

“He (Bryant) definitely seemed extremely frustrated,” Fisher said. “It wasn’t something that he just came up with yesterday.”
