The Philadelphia 76ers will monitor Joel Embiid after the reigning NBA MVP suffered an ankle injury in Friday's 121-111 win over the Toronto Raptors, says head coach Nick Nurse.

Embiid finished with 31 points and 10 rebounds as the Sixers improved to 20-8 with their eighth win in the space of nine games, his 13th straight outing with at least 30 points and 10 rebounds.

That is the longest such run in the league since Kareem Abdul-Jabbar achieved the feat in 16 successive games for the Milwaukee Bucks in 1971-72, with Elgin Baylor (15 in 1961-62) and Wilt Chamberlain (13 on six occasions) the only other players to do so in at least 13 straight.

All of Embiid's points were scored after he landed awkwardly on his left ankle while trying to block a shot with 5:25 remaining in the first quarter. 

With a four-game road stretch awaiting Philadelphia next week, starting against the Miami Heat on Christmas Day, Nurse says the team will keep a close eye on Embiid's condition. 

"Obviously, he stayed in the game and it didn't change his rotation at all," Nurse said of the injury. "But he played through it and I'm pretty sure he'll be sore tomorrow. 

"We'll have to monitor it over the next couple of days before we get on the plane to Miami."

Asked about the extent of the injury immediately after the win, Embiid said: "I don't know. I'll get it checked out. We'll see."

Embiid has now reached the 30-point mark in each of his last 14 games, the most in a row in the NBA since James Harden did so in 32 successive contests in 2018-19.

The six-time All-Star said staying calm and not forcing things after a slow start was the key to his performance, adding: "I saw that I wasn't being aggressive.

"I didn't force anything. I think I took two shots in the first six or seven minutes, but I just let the game come to me.

"It came to me and then in the third quarter, I just found opportunities and made a few shots."
