President Trump has not criticized the N.F.L. in recent months, but he is still having an impact on the league.
On Wednesday, Miami Dolphins wide receiver Kenny Stills criticized his boss, Stephen Ross, who owns the team, for hosting a re-election fund-raiser for the president this weekend on Long Island.
Stills said that Ross’s support of the president is incompatible with the Ross Initiative in Sports for Equality, or RISE, a nonprofit group founded by Ross to use sports to improve race relations.
“You can’t have a non profit with this mission statement then open your doors to Trump,” Stills wrote on Twitter.
