The Chicago Bulls have picked up the fourth-year option on Cameron Payne's rookie contract. Shams Charania of the Vertical reported the Bulls exercised the option for 2018-19 on Friday. Payne has yet to appear in a game for the Bulls this season. He had surgery in September after breaking a bone in his foot during an offseason workout that's expected to keep him sidelined for three to four months. The Bulls currently have Jerian Grant as their starting point guard with Payne on the sidelines. Kris Dunn, who was acquired from the Minnesota Timberwolves in the Jimmy Butler trade, is also out of action with a dislocated finger.
