DALLAS -- All-Star center Alperen Sengun exited early in the first quarter of the Houston Rockets' 110-104 road loss to the Dallas Mavericks on Saturday night because of a lateral sprain of his right ankle.
Sengun was ruled out for the rest of the game before the start of the second half.
He landed awkwardly after grabbing a rebound in traffic. The Rockets called a timeout with 10:56 remaining in the quarter so he could check out of the game.
Sengun, 23, a first-time All-Star last season, is averaging career highs of 21.8 points, 6.5 assists, 1.5 steals and 1.0 block in addition to 9.0 rebounds per game.
Houston backup center Steven Adams missed his second consecutive game with a right ankle sprain, leaving Clint Capela as the Rockets' only available big man.
