WLUK, the Fox affiliate, posted a notice on its Web site, the Star-Ledger of Newark, N.J., reported, proclaiming "Fox to Manning: No Seinfeld for you."
"We don't want to give any comfort to the enemy whatsoever when they come into town," station manager Jay Zollar said. "We know laughter is good medicine, and we decided we're not going to give that to him."
The winning team in Sunday's Giants versus Packers game gets a trip to the Super Bowl.
WLUK is holding a vote among viewers to decide on a replacement for the Saturday "Seinfeld" episode. The choices include a "MASH" rerun, an infomercial and a special on Vince Lombardi with a title designed to lure Cheeseheads, "God, Family and the Green Bay Packers."
