It's finally official — Mike & Mike are splitting up.

It's been the worst kept secret in sports media, but ahead of the network's annual upfront presentation, ESPN formally announced that Mike Greenberg is splitting up with longtime co-host Mike Golic to launch a new morning show on ESPN.

Greenberg's show, which will premiere on Jan. 1, 2018, will air live daily from New York from 7- 10 a.m. Greenberg will be joined by several co-hosts and guests in a show that will combine elements of SportsCenter with segments normally flung in a general-interest morning show.

"My run with Golic has been an incredible experience that I'll always treasure, but having the chance to engage multiple voices every morning in a dialogue on each day's sports stories will be a great new challenge," Greenberg said.

Greenberg's show will offer stiff competition to Fox Sports 1, which announced last week it was launching its own morning show hosted by former Eagles wide receiver Cris Carter and sports radio host Nick Wright. Fox Sports 1 will get a bit of a head start on ESPN, with its morning show scheduled to debut on Sept. 5, days before the start of the NFL season.

Trey Wingo, who anchored ESPN's NFL draft coverage in Philadelphia in place of the semi-retired Chris Berman, will be Golic's new co-host in the yet-to-be-named replacement for Mike & Mike. The show will debut later this fall and will initially be simulcast on ESPN2 before moving to its permanent simulcast home on ESPNU.

The show will also feature Mike Golic Jr., who will join the show daily for an hour from 6-7 a.m. Golic Jr., who lost his ESPN Radio co-host, Robin Lundburg, to last month's round of layoffs, will continue to host First and Last before transitioning to the new show.

"With Mike & Mike ending later this year, I am looking forward to the opportunity to begin the next chapter of the ESPN morning show with Trey and my son Mike," Golic said.

Another new addition to ESPN's lineup is another long-rumored show that will pair ESPN Radio host Bomani Jones and ESPN the Magazine senior writer Pablo Torre.

Jones will have his plate full at the network. In addition to making many appearances on a variety of ESPN shows, he will also continue to host The Right Time with Bomani Jones for three hours every weekday. Jones will give up his co-hosting duties on Highly Questionable at the end of June. So far, the network has not announced a replacement to appear alongside Dan Le Batard.

So ESPN's new morning lineup in January will look like this:

7-10 a.m.: Mike Greenberg's new morning show

10 a.m.-noon: First Take, hosted by Stephen A. Smith and Max Kellerman

Noon-1 p.m.: Bomani Jones and Pablo Torre
