OKLAHOMA CITY (AP) — The Utah Jazz say forward Marvin Williams will not play against the Oklahoma City Thunder on Friday night because of a concussion.
The Jazz say Williams is also doubtful to play Saturday against Houston after he didn't pass an exam following his concussion suffered in a game Wednesday night against New Orleans.
Williams is averaging 10.4 points and 3.8 rebounds this season. He has started 14 of Utah's first 16 games.
