Onyeka Okongwu

Atlanta will be incredibly shorthanded for this game, with Jalen Johnson (calf) and Onyeka Okongwu (mouth) both sidelined. Krejci and Koloko will join the starting group, and there should be extra minutes off the bench available for Mouhamed Gueye and Asa Newell.

Hawks forward Onyeka Okongwu has some serious dental work in his future after taking an elbow to the face during Atlanta's 117-106 win over the Boston Celtics Wednesday.

The Hawks' Onyeka Okongwu suffered a dental fracture, losing at least one tooth, after being elbowed in the face. He will not play vs. the Rockets on Thursday.

Onyeka Okongwu suffered a dental fracture when he was elbowed in the mouth in Atlanta's last game, and will be out at least for the Hawks' matchup with the Houston Rockets on Thursday night. Okongwu was elbowed by Celtics guard Jaylen Brown as Brown possessed the ball in the fourth quarter of a 117-106 Hawks' win on Wednesday night. Brown sustained a maxillary facial fracture two seasons ago after colliding with teammate Jayson Tatum while reaching for an offensive rebound.

The Rockets will already be without Steven Adams, Dorian Finney-Smith, and Tari Eason, so losing Sengun would make them desperately short on big men. Of course, the Hawks will also be without their starting center, Onyeka Okongwu, so both teams could go with smaller lineups. Clint Capela would be in line to start if Sengun misses this game.
