It is unclear whether Simmons, who was suspended by the 76ers for Wednesday's season-opening, 117-97 win over the New Orleans Pelicans for conduct detrimental to the team, will play Friday against the Brooklyn Nets (7:30 p.m. ET, ESPN).
Sources told ESPN that Simmons arrived at and left the team's practice facility Thursday without participating in the planned workout.
The 76ers did not practice Thursday, and Simmons has yet to fully engage in a team practice since reporting last week. He was thrown out of practice Tuesday after he declined several times to sub in for a drill, sources told Wojnarowski.
Amid his trade request, Simmons held out of the first two weeks of training camp. The 76ers have fined Simmons more than $1.4 million for his absence from four preseason games ($360,000 each) and levied numerous fines for missed practices, on-court workouts and meetings, sources told Wojnarowski. He lost roughly $227,000 from Wednesday's suspension.
