LAKE BUENA VISTA, Fla. -- Philadelphia 76ers star Joel Embiid left Sunday's 124-121 loss to the Portland Trail Blazers in the first quarter because of a left ankle injury and did not return.

Embiid appeared to hit his left ankle on the stanchion under the basket midway through the first quarter. After a media timeout with 6:18 to go in the quarter, Embiid slowly walked to Philadelphia's bench and sat in the assistant coach's seat immediately next to the scorers table. He appeared to be in some pain, grabbing at his left foot and grimacing as he was looked at by the team's training staff.

Embiid then was walking around and talking to players and staff, including assistant coach Ime Udoka. Embiid initially sat in his seat in the back row of Philadelphia's bench. Almost as soon as he sat down, however, he got back up and walked out of the bench area and to the locker room.

Late in the second quarter, he was ruled out for the remainder of the game. Embiid returned to the bench in the third quarter.

Embiid had two points on 1-for-6 shooting and four rebounds in 5:42 before he exited the game.
