Philadelphia 76ers superstar Joel Embiid has a rich history of injuries, since the beginning of his NBA career. After colliding with Jonas Valanciunas at the Sixers’ season opener, he may face another knee issue.

According to Ramona Shelburne of ESPN, Embiid could not walk for two days after the 76ers’ season opener. Embiid started against the Nets less than 46 hours after the Pelicans game ended.

However, the situation seems upsetting for the Philadelphia 76ers, with the superstar big being less dominant than usual in the last two games.

With Simmons out indefinitely and in the verge of leaving the organization, the Sixers seemed to be more desperate than ever to keep Embiid on the floor.

Shelburne believes Embiid did not want to miss games pursuing the MVP award as he came second in the MVP voting last year after missing many games due to injury.

In the last matchup vs. the Knicks, he looked pretty far away from his usual dominant self, especially on the offensive end. He finished with 14 points, six rebounds and three assists on a 2-of-7 shooting night.
