He won’t be fined because red is one of the Titans’ team colors. It’s literally in their logo.
From the NFL rulebook...
Rule 5, Section 4, Article 3, Item 7
Item 7. Shoes. Shoes must be of standard football design, including “sneaker” type shoes such as basketball shoes, cross-training shoes, etc. A player may wear shoes that are black, white, or any Constitutional team color, or any combination of black, white, and a Constitutional team color.
If I’m not mistaken, I don’t think fines are handed out until Tuesday. So there’s still a very good possibility he’ll be fined.
But unless he was granted permission to wear them, I think a fine is nearly 100% guaranteed considering neither green or red are one of our team colors.
