Joel Embiid will be out of action for an indefinite period of time after a stray Pascal Siakam elbow fractured the Philadelphia 76ers center's orbital bone.

As well as the fracture, Embiid also suffered a mild concussion, meaning he will miss a minimum of five days as he works his way through the NBA's concussion protocol.

Embiid suffered a similar injury in 2018, which was diagnosed as a facial fracture. In that instance, the team opted to get him into surgery straight away, leading to a three-week absence.

It is reportedly undecided whether the MVP candidate will get surgery, with specialists trying to determine the severity of the injury and the different courses of action that can be taken.

Embiid has also been playing through a torn ligament in his right thumb, which he plans to have surgery on once the 76ers' season finishes.

A source of frustration for 76ers fans is the fact that the injury was sustained with less than four minutes to go, as they led by 29 points, with pundits such as Jalen Rose calling it a coaching failure by Doc Rivers to still have his stars in that game.

Philadelphia's Eastern Conference semi-final series against the Miami Heat begins on Monday night in South Beach, with Embiid almost guaranteed to be unavailable for Game 1.
