Philadelphia 76ers superstar big man Joel Embiid appears to have sustained a minor injury of late, with reports now emerging that the 26-year-old is currently dealing with a calf issue.

NBA insider Keith Pompey reports that Embiid will not be able to participate in the Sixers' scrimmage game on Sunday against the Oklahoma City Thunder:

It does not sound serious, and it appears that the Sixers are just holding out their prized big man to err on the side of caution. If this were already a seeding game, then it is likely that Embiid would suit up for his squad.

Pompey also reports that Embiid suffered the injury on Friday in Philadelphia's 90-83 scrimmage win against the Memphis Grizzlies.

Head coach Brett Brown warned about getting in front of the injury before it becomes serious.

Embiid played just 13 minutes in that contest, logging 10 points (on 3-of-10 shooting), six rebounds, and an assist. The calf issue may have played a role in Embiid's limited minutes during the victory.

Philly's game against the Thunder on Sunday will be their last scrimmage prior to officially restarting their season on Saturday. The Sixers are set to face off against the Indiana Pacers in the first of their eight scheduled seeding games. It remains to be seen if Embiid will be forced to miss any of his team's seeding games, but at the moment, all signs are pointing to the fact that this is something minor.

Philadelphia is currently ranked sixth in the Eastern Conference with a 39-26 record. It's pretty tight in the East right now, and the seeding games will be crucial in determining the positioning for the playoffs.
