Siakam has been the Raptors' second-best player throughout the playoffs, averaging 22.9 points per game, 7.4 rebounds, 2.5 assists on 52.4 percent shooting from the field.

It's an immeasurable loss for the Raptors, who are trailing the Sixers 2-1 entering Sunday's contest.

Siakam confirmed to reporters Saturday that his calf is swollen.

“A lot of contact during the game, I don’t know exactly when anything happened but after the game, I was just really sore,” Siakam said.

With Siakam’s status in doubt for Sunday’s game, Kyle Lowry told reporters he’d be more aggressive with his shot selection.

“A little bit more aggressive, though. Might take some shots that I haven’t taken in a year and a half, forcing - not forcing, but taking some shots that may be tougher than they are and that’s going to be the mindset, no matter if Pascal played or not,” Lowry said.

Siakam was the subject of controversy after tripping Joel Embiid during Game 3, and that’s where he may have injured his right calf. Siakam earned a Flagrant 1 on the play.

Jeremy Lin has also been listed as questionable with back spasms, according to Blake Murphy of The Athletic.
