Saturday's San Francisco 49ers preseason game featured an ugly scene in the stands at Levi's Stadium.

Numerous Niners fans had to be separated after a huge brawl during the game against the Denver Broncos.

It's unclear what started the ruckus, but in the beginning of a video, at least three people can be seen throwing punches. 

From the looks of it, two fans — one wearing a Steve Young jersey, the other wearing a Jerry Rice jersey — were involved.

At least three children had a front row seat for the fight.

One fan was whisked away, but that left two others — the man in the Rice jersey and another in a white shirt — throwing numerous haymakers.

Eventually, it was broken up by security, but not before the man in the white shirt came up bloodied with his shirt ripped near the collar.

A separate view of the beginning of the brawl seems to show a disagreement between the fan in the white and the fan in the Young jersey.

The 49ers won the game over the Broncos, 21-20.

There's no hope for James Harden and the Philadelphia 76ers to work out their differences, the star guard says.

The 10-time All-Star requested a trade from the team earlier this offseason, but nothing materialized.

The team plans to bring him into training camp.

When making an appearance on a radio show in Houston, where he used to play, Harden was asked if it is "too late" to fix the relationship with his team.

"I think so," he replied.

Harden recently made headlines for calling team president Daryl Morey a "liar," adding he "will never be a part of an organization that (Morey's) a part of."

It's unclear what prompted Harden's comments, but the situation is being investigated by the NBA. 

Morey, as an executive with the Houston Rockets, caused a stir in 2019 when he posted a pro-Hong Kong message as protesters demonstrated against a law that would allow extradition of fugitives wanted in China. The protests turned violent.

That prompted a blackout of the NBA in China, and the league's relationship with the country has not been the same since.

At the time, the NBA was in the middle of a preseason tour that included the Los Angeles Lakers and Brooklyn Nets. Advertisements of the games were taken down. The Rockets were in Japan at the time, and Harden was among team members who broke from Morey’s tweets.

Morey, who spent eight seasons with Harden with the Rockets, said he was "attempting to honor" Harden's trade request but only if Philadelphia receives significant compensation in return.

"I do have a long relationship with him. I’m attempting to honor that," Morey said in a radio interview with 97.5 The Fanatic in July. 

In his two seasons in Philadelphia, Harden has averaged 21.0 points, 10.6 assists and 6.4 rebounds per game alongside Joel Embiid, who was named the NBA’s MVP last season. 

The Sixers failed to reach the Eastern Conference finals for the 22nd consecutive season when they lost in seven games to the Boston Celtics in May.

With the team once again falling short of expectations, the Sixers' front office made an immediate change, firing head coach Doc Rivers after three seasons and replacing him with Nick Nurse.

Harden turns 34 Saturday and is entering his 15th NBA season.
