Antonio Brown, a wide receiver for the Pittsburgh Steelers, was told to remove his Muhammad Ali-inspired cleats during Sunday's game against the New York Jets, according to the Bleacher Report.
Brown was asked to change into standard Nike cleats, Dean Blandino, the NFL's senior vice president of officiating told ESPN.
This is the fourth time Brown has been in trouble with the NFL for his footwear.
During Week 1, Brown was fined for wearing baby blue cleats in a game against the Washington Redskins.
In week 3, he wore baby blue cleats with the faces of all four of his children on them. A uniform inspector asked him to remove them.
Brown tweeted a photo of the cleats saying, "The four reasons I lace them up every day."
Last week Brown wore black and gold cleats with a design to honor legendary golfer Arnold Palmer. Officials asked Brown to remove his cleats then too.
According to ESPN, if a player refuses to change his uniform after an inspector tells him to do so, he can be sidelined for the rest of the game.
ESPN reported that Brown faces nearly $50,000 in fines for touchdown celebrations and uniform violations so far this season.
