Brandon Marshall lost a bet, and it's going to cost him the price of a Porsche

Jets wide receiver Brandon Marshall shows he's a man of his word.

Brandon Marshall made a costly bet with Pittsburgh Steelers wide receiver Antonio Brown this season that he lost, and Marshall says he fully intends on paying up.

During the preseason, the New York Jets wideout bet Brown his Porsche that he would have more receiving yards, but fell way short with 788 yards to Brown's 1,284. On HBO's Inside the NFL Thursday, Brown reminded Marshall to keep his word.

"Brandon, it's your guy AB," Brown said. "I know you're the ultimate competitor. You made the bet, own up to it. Send me the pink slips, or we can donate the car to your charity. However you want to do it. Just let me know."

And Marshall was quick to respond, telling Brown he would donate the value of his Porsche (a reported $100,000) to Project375, Marshall's own charity.

But Marshall also took a swipe at Brown, suggesting that having a Hall of Fame quarterback throwing to him made all the difference.

"The bet should have included a Hall of Fame quarterback, Ben Roethlisberger," Marshall said. "Anybody can (make) 100 catches for 1,200 yards a year when you have Big Ben."

He's not entirely wrong.
