PHILADELPHIA -- Toronto Raptors forward Pascal Siakam, who is nursing a right calf contusion, will be a game-time decision for Game 4 of the conference semifinals between the Raptors and the 76ers.

"We're still waiting," Raptors coach Nick Nurse said. "He hasn't been on the court yet. They're going to take him out there and see how he's doing. Obviously we had a team meeting this morning. He said it wasn't any worse than it was. It's a good start.

Siakam injured the calf in the Raptors' 116-95 loss at Philadelphia in Game 3 on Thursday. He did not dress for the Raptors' Saturday practice at Wells Fargo Center.

After Siakam tests the calf during pregame warm-ups, the team's medical staff will evaluate his condition. Should Siakam be unable to play, Nurse said he is considering several contingencies for the Raptors' starting lineup.

"Possibly [Serge] Ibaka, possibly [Fred] VanVleet, possibly one other guy," Nurse said.

In Toronto's eight games this postseason, Siakam has averaged 22.9 points, 7.4 rebounds and 2.5 assists, with an effective field goal percentage of 56.9.

Toronto trails the series 2-1.
