Simmons will sit out against Denver and will be evaluated again before Sunday's game against Charlotte. He was hurt Wednesday in Philadelphia's 106-104 loss at Utah. Simmons did not play in the second half after bumping into Royce O'Neale's chest while posting up on a first-quarter play. Simmons passed the ball after the contact and then immediately grabbed his shoulder.
He ended up playing 10 minutes, scoring two points with two assists and a rebound.
The All-Star guard averaged 13.1 points and helped lead the Sixers to a 5-2 record.
