Sports blog threatens NFL over slogan

Saturdays are for the boys, not for the National Football League.

That’s according to the sports blog Barstool Sports, which sells its own apparel declaring “Saturdays Are For The Boys,” a slogan its founder says the NFL “stole,” as reported by TMZ.com on Wednesday.

Barstool President Dave Portnoy, who claims the blog has a trademark for the slogan, said he and his team were “shocked” when they spotted "Sundays Are For The Boys" shirts on the NFLShop.com website, the official online store of the NFL, the website reported.

Mr. Portnoy told TMZ.com he's gearing up to file a lawsuit unless the NFL rips the shirts off the online shop “immediately.”

NFL did not comment on the story as of Thursday.
