The Philadelphia 76ers' hot start to the NBA season has dramatically chilled with Ben Simmons suffering a shoulder injury in a loss to Joe Ingles' Utah Jazz.
The Jazz held on for a 106-104 victory in Salt Lake City on Wednesday.
It was the 76ers' second straight loss after opening the new season with five consecutive wins.
