The shooting guard is listed as questionable for Friday morning's preseason game against the Dallas Mavericks at the Mercedes-Benz Arena.
If he's unavailable to play, Redick would become the fifth Sixer to miss the game. Wilson Chandler (strained left hamstring), Jerryd Bayless (sprained left knee), Zhaire Smith (Jones fracture, left foot), and Norvel Pelle (gastroenteritis) did not make the trip to China for the two matchups against the Mavericks. The team will conclude the trip after Monday's game in Shenzhen at the Shenzhen University Center.
Redick signed his second consecutive one-year deal with the Sixers in July.
