NEW YORK (CNNMoney.com) -- Super Bowl network CBS rejected an ad Friday from ManCrunch.com, a gay dating Web site.

"After reviewing the ad, which is entirely commercial in nature, our standards and practices department decided not to accept this particular spot," said CBS spokeswoman Shannon Jacobs. "We are always open to working with a client on alternative submissions."

CBS said it turned down the ad partly for financial reasons, but ManCrunch believes that there's more to it than that.  "It's straight-up discrimination," said Elissa Buchter, spokeswoman for the Toronto-based dating site.  Jacobs of CBS declined to comment on the charge of discrimination.

Shortly before ManCrunch announced the rejection, Jacobs of CBS said her company was reviewing the ad and it was "just one of many."

Jacobs also said the spots were "virtually sold out. We have one, maybe two spots left."

ManCrunch is not alone. Godaddy, an online retailer of Web site domain names, is running an ad in the Super Bowl this year but it had another ad rejected by CBS in the process. The rejected ad features a man named Lola.

This year's Super Bowl, between the Indianapolis Colts and the New Orleans Saints, will be played Feb. 7 at Sun Life Stadium near Miami. The facility in Miami Gardens, Fla., formerly called Dolphin Stadium, was recently renamed.
