Barrett (illness) has been ruled out for Sunday's game against the Rockets, Blake Murphy of Sportsnet.ca reports.
Barrett was initially slated to return from a one-game absence Sunday due to an illness. However, it appears he is still under the weather, and his next opportunity to play will be Monday against the Knicks. Ja'Kobe Walter was inserted into the Raptors' starting lineup against the Nets on Thursday, and he should resume that role Sunday due to Barrett's illness.
