TORONTO -- Cavs forward/center Channing Frye was excused from the team to address a "personal matter" and will not play in tonight's game against the Raptors.

UPDATE: Frye's mother, Karen Mulzac-Frye, passed away after a long battle with cancer, the team said. Frye did not travel with the Cavs to Toronto. The team confirmed Frye's mother's death shortly before 1 p.m. Frye is excused from the team indefinitely -- he will not play Saturday at home against Orlando.

Frye scored six points and grabbed four rebounds Tuesday in Cleveland's season-opening 117-88 win over the Knicks. He kept his mother's illness from teammates and coaches until this week.

"For him to internalize it this whole time without saying anything to anyone is tough," Cavs coach Tyronn Lue said. "It's something we have to go through as professional players and athletes, you've got to deal with these things. These are everyday things we have to deal with and it's just tough anytime you lose your mom or any family member."

Lue's mother and grandmother are battling cancer, too.

Lue said Iman Shumpert (concussion symptoms) would play against the Raptors.

"He's like the bionic man or something, I don't know," Lue said of Shumpert, who banged his head on Kristaps Porzingis' hip Tuesday night but isn't going to miss any games. "He heals fast. He heals quick. So that's good for us. You never want to see anyone get injured but that happens in the games. It's good he was able to bounce back as quick as he did."
