Monday Night Football” play-by-play announcer Mike Tirico will leave ESPN to join NBC, according to multiple media reports.

Tirico, whose current contract runs through this summer, has been with ESPN and served as the play-by-play announcer on its “Monday Night Football” broadcast since 1996.

It is not yet known what role Tirico will take on at NBC. Al Michaels, who is 71 years old, currently is the play-by-play announcer on the network’s flagship “Sunday Night Football” broadcast. NBC veteran Bob Costas is set to serve as the lead anchor on the network’s coverage of the upcoming Summer Olympics in Brazil.

NBC did recently pick up rights to split “Thursday Night Football” NFL games with CBS for the upcoming season — a privilege that the network paid a reported price of $225 million for. That package will give NBC five Thursday-night games over each of the next two seasons.

Tirico also is a play by play announcer for ESPN’s coverage of NBA basketball, and will continue in that role through the NBA playoffs. He has also called college basketball, college football, golf and tennis for ESPN. Though NBC does not hold any NBA or college basketball rights, it does have PGA and British Open golf packages.

NBC declined to comment to Variety. Sports Business Daily first reported the news.

According to Sports Business Daily, ESPN’s Sean McDonough is a lead candidate to replace Tirico on “Monday Night Football.”
