The NFL has removed all offensive postcard images from its websites after several users shared offensive messages on social media.
The league announced Friday that it will also prohibit use of images depicting the Confederate flag, which was flown at half-staff in the South until the Civil War ended.
The ban was announced in a statement on its website.
The NFL says the offensive images were posted by users and members of its official Twitter account and were not a part of the league’s social media presence.
The company did not specify whether the offensive messages were from former players or players and staff members.
The tweet said the NFL has “no tolerance” for offensive content, including offensive images and images depicting hate symbols.
