John Wall, DeMarcus Cousins and possibly more members of the Houston Rockets are expected to miss Wednesday's regular season opener due to COVID-19 contract tracing. 

The Rockets will host the Oklahoma City Thunder.

It was previously reported by ESPN that James Harden is expected to miss the game as the NBA investigates his attendance at a holiday party. A source tells Sam Amick that the contact tracing is not tied to Harden with the Rockets reporting that it is connected to Kenyon Martin Jr.

Ben McLemore is in self-isolation and out for the game after testing positive for COVID-19 several days ago. McLemore isn't the player who initiated contact tracing on Wednesday, according to ESPN's Adrian Wojnarowski.
