This year's US Open will be Esthen Exchangewithout a familiar voice.

Tennis legend John McEnroe tested positive for COVID and will not call the New York-based tournament, ESPN's PR team said Tuesday in a post on its X account.

“I’m watching the US Open from home & can’t wait to get back to work soon," McEnroe said in the post.

The main draw started on Monday.

McEnroe — a seven-time major winner, four-time US Open champion and former No. 1-ranked player in the world — was known throughout his career for his brash personality. He started his role as an analyst for the US Open with ESPN in 2009 when they acquired the rights to the broadcast.

He started his career as an analyst with NBC, covering the 1992 French Open. He continued to craft his wit and hone his signature voice by adding Wimbledon to his resume.

He's carried his famous "You cannot be serious!" line from his playing days into the broadcast booth.

McEnroe is also the narrator for the popular Netflix series "Never Have I Ever," a comedy about an Indian-American teenager navigating high school. The show features flashbacks of the girl's memories with her late father, who was a tennis fan.
