Tennis Channel took analyst Jon Wertheim off the air “indefinitely” after Wimbledon champion Barbora Krejcikova called him out on social media for what she called “coverage that focused on my appearance rather than my performance.

Wertheim, a prominent American tennis journalist, made his ‘deeply regrettable comments’ on the Tennis Channel’s coverage of the WTA finals, unaware he was on the air.

Jon Wertheim, who was heard making unflattering remarks about Barbora Krejcikova’s appearance, issued an apology for what she described as “unprofessional commentary.”
