Doc Rivers has been a part of the NBA for 33 years as a player and coach. He thought he had seen everything until Friday night.

The Los Angeles Clippers coach and Chicago Bulls coach Jim Boylen were both ejected during the third quarter at Staples Center for arguing. It is something so rare that the NBA and Elias Sports Bureau could not recall or track the last time it has happened.

"I've been around a while and I needed something new," Rivers said after the Clippers' 128-121 victory.

The Clippers led 91-76 with 1:10 remaining in the quarter when Boylen thought that Clippers forward Montrezl Harrell was too aggressive on an offensive foul and started yelling across the other side of the court at Rivers and the officials.

Both started arguing near their respective benches when official Jason Phillips assessed the first technical. Boylen and Rivers continued to argue, which caused Phillips to assess the second technical and an automatic ejection.

Rivers said he had no idea why he was ejected for the second time this year, especially since he said he wasn't the one who instigated the argument.

After both coaches were ejected, Pete Meyers took over for the Bulls and Rex Kalamian for the Clippers.

"I have no issue with Doc. He's fighting for his team and I'm fighting for my team," Boylen said.

Ingram undergoes surgery

Los Angeles Lakers forward Brandon Ingram is expected to be ready for next season after undergoing surgery on his right arm.

Ingram had thoracic outlet decompression surgery Saturday, the Lakers say.

Ingram was declared out for the season earlier this month after he was diagnosed with deep venous thrombosis. A blood clot caused shoulder pain for Ingram, who averaged a career-best 18.3 points and 5.1 rebounds this season.

Ingram's surgery was performed at the Ronald Reagan UCLA Medical Center.

The Lakers say he is expected to make a full recovery before the start of his fourth NBA season in the fall.

Ingram was the No. 2 pick in the 2016 draft out of Duke. He turns 22 in September.

Durant sidelined

Golden State Warriors forward Kevin Durant sat out Saturday night against his former team, the Oklahoma City Thunder, with a right ankle sprain.

Durant, the league's No. 4 scorer, also missed Golden State's game against Houston on Wednesday. Warriors coach Steve Kerr said Durant will most likely play Monday against San Antonio, but he felt more comfortable giving him a few more days of rest.

Durant also sat out at against Oklahoma City in March 2017 with a left knee injury.
