Westbrook made the revelation on social media. As recently as Sunday, the Rockets believed that Westbrook and James Harden - neither of whom traveled with the team to Walt Disney World near Orlando last week - would be with the team in the next few days.

In Westbrook's case, that now seems most unlikely.
"I tested positive for COVID-19 prior to my teams departure to Orlando," Westbrook wrote on his Instagram page. "I'm currently feeling well, quarantined, and looking forward to rejoining my teammates when I am cleared."
Westbrook is averaging 27.5 points, eight rebounds and seven assists per game for the Rockets this season. Houston has clinched a playoff spot and resumes its season with the first of eight seeding games on July 31 against Dallas.
Westbrook also offered a word of caution in his post.

"Thank you for all the well wishes and continued support," he wrote. "Please take this virus seriously. Be safe. Mask up!"
