Watch: Embiid plays tennis at night on outdoor Philly court

Joel Embiid continues to immerse himself in his NBA city.

The Philadelphia 76ers center took to an outdoor hard court and played tennis Tuesday night.

Embiid said his tennis game is strong.

"I'm a really good server," he told reporters, including NBC Sports Philly. "They call me the black Roger Federer."

The previous evening, Embiid was spotted (and filmed) running through the streets of Philly at around 9:30 p.m.

It's nice to see him out there moving, given his injury history. The 23-year-old was shut down after suiting up for just 31 games last season, and underwent knee surgery in March. He still hasn't been cleared to play five-on-five, and has been ruled out for the Sixers' two preseason games this week.
