Down 2-0 in the series against the Miami Heat, the 76ers may have to face another game without star center Joel Embiid.Joel Embiid Injury UpdatePhiladelphia revealed the injury report for Game 3, listing Embiid as out with a facial fracture and concussion. However, according to ESPN's Adrian Wojnarowski, there's still a chance his availability status could change ahead of the Friday game.The dominant big man was exhibiting concussion symptoms as recently as Monday, according to Chris Haynes. Haynes alluded to the struggles on NBA on TNT yesterday, saying Embiid was unable to use his phone until Tuesday because the brightness was “causing problems.”The norm, in both the NFL and NBA, is to rule a player out until he officially clears concussion protocol. Embiid could still be cleared in the next 24 hours and make a return for the must-win Game 3, but that news may not come until close to tip-off. Reporters have indicated that Embiid is still in the throes of the concussion protocol, thus the possibility remains that he will cleared in time for Game 3 Friday night.The Pro Basketball Docs were optimistic about his chances for a Game 3 return. He didn’t require surgery on the right orbital fracture, meaning his return-to-play timeline for the orbital fracture is 7-10 days.Friday will mark eight days since he suffered the injury on this play late in the Game 6 win over the Raptors.The play where Joel Embiid got injured pic.twitter.com/GYWDUxupoU— NBACentral (@TheNBACentral) April 30, 2022 If he plays, Embiid would carry a SIC player health score of 84 for the game, with the main downgrade for his lingering right thumb injury, according to the Pro Basketball Docs.His thumb will affect his game more than the orbital fracture, limiting his 3-point shooting ability and potentially creating ball security issues.The facial fracture and concussion will likely be non-issues when he makes his return, according to the Pro Basketball Docs,If he returns in the series, the 28-year-old, 7-footer will play with a mask on to protect the orbital fracture. The mask is not 100% effective and wrong blow could make the orbital fracture worse and require him to undergo surgery. Embiid does have experience playing with a mask on. He did so in the 2018 playoffs after suffering a left orbital bone fracture in March 2018.In that playoffs, the 76ers beat the Miami Heat in the opening round before losing to the Boston Celtics. Embiid had double-doubles in seven consecutive games to close out the playoff run.Heat vs 76ers Game 3 OddsThe 76ers are 3 point underdogs at home in Game 3 and the over/under is 209.5, according to FanDuel Sportsbook, but that is likely with the expectation that Embiid will miss the contest. Philadelphia is at +810 to win the series and +5000 to win the NBA Finals.
