HOUSTON (AP) — Houston’s season opener against the Oklahoma City Thunder on Wednesday night has been postponed after coronavirus cases and James Harden’s violation of the NBA’s COVID-19 protocols left the Rockets without the league-mandated eight players available for the game. The NBA announced the postponement in a release that said three Rockets players had returned tests that were either positive or inconclusive and that four other players were quarantined because of contract tracing.
