Walter (shoulder) has been ruled out for Monday's game against the Pacers and remains sidelined indefinitely, Blake Murphy of Sportsnet.ca reports.
Walter doesn't have a return timetable while he works his way back from a shoulder injury. Walter worked his way into Toronto's rotation in early November due to the Raptors' myriad of absences, but when everyone is healthy, the rookie will have an uphill battle to see minutes consistently.
