Travis Kelce's used to scaring defenders on NFL fields, but it seems he'll be frightening a whole lot more people off of them this fall -- 'cause a teaser for "Grotesquerie" just dropped, and the NFL star looks like he'll be playing a spooky character in the show!!
The folks over at FX leaked the first trailer for the new horror series on Thursday ... and while Kelce's appearance in the 87-second commercial is brief, it looks like Taylor Swift's boyfriend will be terrifying audiences with his role.
