Okafor, a former No. 3 overall draft pick, has only appeared in two games this season after losing his spot in the Sixers’ rotation.
The former Duke standout has averaged 14.6 points, 5.9 rebounds and 1.2 assists per game during his three NBA seasons.
Last month, Okafor told ESPN that he’s been wasted on the bench this season as the Sixers refused to agree to a buyout or trade him prior to Thursday.
“This is my third year in the NBA, and I know it’s a business,” Okafor said. “I don’t know if it’s fair or not, but in talking to other people in the NBA, talking to retired players, one thing I’ve heard them say is that what’s going on with me isn’t right and they’ve never seen anything like this before.
“I know it’s business, but in my eyes, I don’t know if it’s good business.”
Booker, who signed with the Nets last offseason, is averaging a career-best 10.1 points, as well as 6.6 rebounds through 18 games in the 2017-18 season.
Stauskas has appeared in six games off of the Sixers’ bench and has averaged 7.3 points, 2.1 rebounds and 1.7 assists per game during his four-year NBA career.
