Houston Rockets teammates James Harden (left) and Russell Westbrook both tested positive for the COVID-19 virus.
On Monday, Westbrook announced his positive test result on social media. Later that day, Elite Media reported that Harden had also tested positive.
Westbrook and Harden say they have no symptoms and they feel well. The majority of people with COVID-19 experience no symptoms or mild symptoms.
Both players are expected to join their teammates at the NBA bubble in Orlando, Florida next week.
When they arrive in Orlando they will be quarantined until both players test negative twice.
Most of the team and staff have already arrived at the facility to begin workouts for the restart of the NBA season which was canceled amid the coronavirus outbreak in the US.
They are likely to miss the first game against Dallas.
On Monday, the NBA announced two other players tested positive. Both players are in 14-day quarantine away from the bubble.
