Tennessee Titans linebacker Avery Williamson is not expected to be fined by the NFL for wearing 9/11 cleats Sunday during the 15th anniversary of the Sept. 11 attacks, according to multipe reports.

TMZ first reported the news Tuesday.

Titans coach Mike Mularkey supported Williamson and said he would pay any potential fine for the shoes, which were painted red, white and blue and had "Never Forget" written on the rear of the cleats.

Williamson wasn't the only player to wear cleats honoring victims and first responders of the attacks. He joined Giants wideouts Odell Beckham Jr. and Victor Cruz among others.

In the past, the NFL has been very strict regarding its uniform policy, fining players such as running back DeAngelo Williams, who wrote "Find the Cure" on his eye black last season to bring awareness to breast cancer. Williams' mother died of the disease in 2014.

According to Sports Illustrated, the league will allow players to wear personalized messages on players' cleats on Week 13 of this season to promote a charitable cause of their choice. The league must approve the cause before Week 13 and players must auction the cleats, donating 100 percent of the proceeds to the charity, according to the report.
