The Toronto Raptors’ issues with the coronavirus have worsened, prompting the NBA to call off their game scheduled for Sunday night against the Chicago Bulls. The league said the Raptors are dealing with positive test results, without disclosing how many, and that combined with ongoing contact tracing issues meant they would not have the league-required eight players available to play. Toronto played Friday without head coach Nick Nurse, several other assistants and staffers and starting forward Pascal Siakam because of virus-related issues. Assistant coach Sergio Scariolo coached the team to a win over Houston and was in line to coach again Sunday.
