Wroten was injured in Friday's loss at home to the New York Knicks and did not travel with the team. Coach Brett Brown says he will miss all three games on this trip and ''after that, I don't know.''
Wroten is one of the few bright spots on a team that entered with 23 straight losses, tying the NBA's second-longest streak. He is averaging 13.4 points.
The Sixers visit San Antonio and Houston before returning home to play Detroit on March 29.
