Bronny James Dances At Big USC Hoops Event, But Sits Out Of Competitions

Bronny James was teachin' fans how to Dougie at a USC hoops event Thursday night ... dancing his tail off during player introductions -- but he sat out all of the night's competitions, an indication he's still not quite 100 percent after suffering cardiac arrest.

LeBron's oldest son received a super warm welcome at the annual Trojan HoopLA shindig at the Galen Center in downtown Los Angeles ... and he sure seemed to love it all, gyrating to Cali Swag District's "Teach Me How To Dougie" as people in the stands roared.

However, that was about all the physical activity he did during the evening ... electing not to participate in the skills competition, dunk contest and the 3-point contest.

Of course, it's not unexpected at all ... Bronny required surgery just a few weeks ago after he had the issue with his heart back in July -- and everyone involved has been making sure he's been brought along slowly ever since.

It's unclear when he'll be able to officially start putting basketballs in hoops for the Trojans this year ... a timetable has not been given -- but LeBron said just days ago the goal is for his son to make an impact at USC soon.

Meanwhile, there were plenty more highlights from the Trojans event Thursday ... including when freshman forward Brandon Gardner threw down a massive slam over star USC quarterback Caleb Williams during the dunk contest.
