Clippers coach Doc Rivers said Leonard will play in the NBA pre-season game.
"I don’t know how much, but he’s definitely playing tonight," he said before L.A. hit the court for a pre-game shootaround.
Leonard led the Raptors to their first NBA championship last season, averaging 30.5 points per game in a playoff run which generated huge television ratings across Canada.
The 28-year-old opted to join his hometown Clippers in free agency, reportedly agreeing to a three-year, US$103-million contract.
The negotiation period attracted plenty of attention. One television network even used a helicopter to film a vehicle that reportedly had Leonard inside after he flew to Toronto to meet with the Raptors.
Rivers knows Canadian fans will be looking forward to seeing Leonard live on Thursday.
"They should be excited," the coach said. "He did something very special for this country. So that’ll be a lot of fun for him, for sure."
Leonard is returning to the city where he took part in his first and only training camp with the Raptors last year.
