Derek Hough announced he tested positive for COVID-19.

His announcement comes after he judged Monday night’s taping of “Dancing with the Stars.”

He revealed his diagnosis on Instagram.

“Hey everyone, I have some news to share and I wanted you to hear it straight from me. Um, even though I’ve been fully vaccinated, I’ve just been diagnosed with a breakthrough case of COVID.”

He noted that he’s taking advice from medical professionals and doing everything he can to get better fast.

He canceled his upcoming Vegas shows, but failed to mention what this means for his ‘DWTS’ duties.

His diagnosis could impede upcoming tapings of the hit dance show.

His positive COVID test could potentially mean show tapings and performances are pushed back while the entire cast and crew get tested for the virus.

ABC and ‘Dancing’ have not yet issued any formal statement.
