The Marlins broke down their decision on their team's account:
Marc Topkin of the Tampa Bay Times reported the Rays took a similar action.
The news comes one day after the pizza company's founder, John Schnatter, resigned as the company's chairman, per Nathaniel Meyersohn of CNN Money. Schnatter reportedly used the N-word while on a conference call with a marketing agency.
He had also previously resigned as CEO of the company in December following comments about NFL players' protests during the national anthem.
According to ESPN.com's Darren Rovell, Schnatter resigned from the University of Louisville's board of trustees Wednesday, although the football stadium currently remains Papa John's Cardinal Stadium.
Meanwhile, Major League Baseball had been utilizing a "Papa Slam" promotion since 2016, giving discounts on pizzas when players hit a grand slam.
However, the league announced Wednesday it has indefinitely suspended the promotion, per Mike Oz of Yahoo Sports.
The Marlins and Rays are the latest sports organizations to sever ties with the company.
