YOU STRAY YOU PAY! NFL SPORTSCASTER JIM NANTZ GOT TO SHELL OUT A MILLION BUCKS A YEAR FOR THE REST OF HIS LIFE TO HIS EX-WIFE!

NFL on CBS sportscaster Jim Nantz made one really bad call -- with a 29-year-old woman -- and now it will cost him nearly a million bucks a year for the rest of his life.
A Connecticut judge ordered the famous announcer to pay his ex-wife $864,000-a-year in alimony -- and the only way out is death ... or if his ex-wife remarries.

The judge's decision comes in light of Nantz's admission that he began dating a 29-year-old woman before he ended his 26 year marriage. Smooth...

Nantz also has to pay $1,000-a-week in child support for their 15-year-old daughter for the next two years.

Jim's wife also gets the couple's Westport mansion -- no word if he gets to keep the couch he's probably been sleeping on.
