ANN ARBOR, Mich. (AP) — Mike Tirico is leaving ESPN and ABC Sports this summer when his contract expires to work for NBC, a person familiar with the move told The Associated Press on Monday.

The person spoke on condition of anonymity because neither network had made an announcement about the broadcaster. SportsBusiness Journal was first to report the news.

Tirico began working at ESPN in 1991 and became its “Monday Night Football,” play-by-play announcer a decade ago.

He seamlessly transitions to calling action for major golf and tennis tournaments, NBA and college basketball and college football.

“He never seems to get flustered or rattled,” former broadcast partner Joe Theismann once said. “He’s incredibly smooth.”

Tirico was part of a new-look broadcast as “Monday Night Football” moved from ABC – its home for 36 seasons – to ESPN.

“If I’m doing my job, I’ll be like an offensive lineman or an official,” Tirico said in 2006 during an AP interview before making his “Monday Night Football,” debut. “You’ll know I’m there, but you won’t really notice me.”
