Philadelphia 76ers center Joel Embiid completed his first full practice on Thursday since undergoing surgery in March after tearing his meniscus in his left knee. 

Embiid took to Twitter to tell his fans that he was, "I'm on a basketball court doing things ... I'm back."

Embiid was cleared for 5-on-5 drills, but he will not play in the 76ers' second preseason game against the Celtics on Friday. Coach Brett Brown said he wants to work slowly with Embiid so that he's ready to go on Oct. 18 for opening night in Washington, but he isn't ready to pinpoint an exact date, according to The Philadelphia Inquirer. 

"I trust them, but at the same time, I have a voice, too," Embiid said Thursday. "I think they value my opinion. It's about being on the same page." 

Embiid acknowledged that he felt rust, but from the part of practice scrimmage available to media, he looked dominant on the court making 3-pointers and blocking shots. He didn't appear to have any limitations.
