Credit to Rob Tornoe– he beat on finding out the deal with Mike Missanelli:

According to sources at the station, Missanelli underwent major back surgery in December. Despite a recovery time of typically 6 to 8 weeks, Missanelli returned to the station in late January, but only made his back worse after about two weeks on the air.

…

Sources say they expect Missanelli to return to the station sometime in March. Until then, Jason Myrtetus will continue to fill in alongside midday co-host Harry Mayes.

I reached out to Mike to see how he’s doing, but didn’t hear back right away. I’ll update the post if I do.

According to my Twitter mentions and comments, people like what they hear from Myrtetus and Mayes. And it’s not like Missanelli’s absence in December hurt ratings at all– Chris Carlin and Ike Reese on WIP were still getting doubled by 97.5’s B team.
