The Philadelphia 76ers have been hit by another serious injury. According to the Sixers, rookie guard Jared McCain reported left knee pain to the team following Friday night’s loss to the Indiana Pacers.

After an MRI scan, McCain was diagnosed with a torn lateral meniscus in his left knee. According to the team, he will undergo surgery and will be out indefinitely.

McCain’s injury occurred during the first-year guard’s Rookie of the Year campaign. Over the last 16 games, McCain has played an integral role with the Sixers. During that entire time, he averaged 19 points per game while shooting 46 percent from the field.

McCain attempted eight three-pointers per game and shot his distance shots with a hit rate of 40 percent. He also managed three rebounds per game and dished out an average of three assists.

While McCain is widely considered the favorite to win the NBA’s Rookie of the Year Award, his recent injury could certainly jeopardize his chances of taking home the award.

The Sixers’ rookie is the second key player to suffer an injury in Friday’s loss to the Pacers. In the second quarter of the game, the Sixers saw star center Joel Embiid go to the ground after taking a hit to the face. Embiid went back to the locker room to be evaluated.

In the third quarter, the Sixers shut Embiid out for the rest of the night. As the fourth quarter approached, McCain was the second player to go to the locker room. The star guard hit his head and had to be checked for a concussion. McCain returned to the court shortly after to finish the game.

Embiid did not return to Friday’s game. The big man was examined for a facial fracture. The Sixers’ medical staff described Embiid’s injury as a sinus fracture. He will be further evaluated this weekend. His timetable for a return is currently unknown.

The Sixers face the Charlotte Hornets on Monday night.
