It looks like Epic and the NFL are going to expand their partnership. The first part of this updated relationship will be a new batch of NFL skins called the Gridiron Gang. These are not the same as the original NFL skins that came out in the past, but have updated models and new sportier uniforms. There will be two styles for each team, and they will come with a new Back Bling of the team's logo. You can also customize the jersey number, and toggle if you want a reflective visor on the helmet!
Here are the details on the new skins from the press release that was posted by the NFL:
Starting November 25th in Fortnite, new Gridiron Gang Outfits will be available for purchase from Fortnite's in-game shop. These new, redesigned NFL uniforms feature a more athletic, aerodynamic look and feel. All 32 NFL teams are represented with two styles to select, along with the new Logo-a-go-go Back Bling that lets you rep any team's logo. Additionally, these Outfits let players customize the jersey number and toggle whether they want a reflective visor on the helmet.
As mentioned above, you will see this skins available in the item shop on November 25th, 2020. I imagine they will be available for at least a few days, so start saving up your V-Bucks if you are a big fan of the NFL!
If you already have a NFL outfit from before, then you would still be required to purchase one of these new ones to get all the new styles. These are totally different skins, so you won't get anything new if you own an old outfit unfortunately!
