Philadelphia Eagles center Jason Kelce and Kansas City Chiefs tight end Travis Kelce will make NFL history in Super Bowl LVII at Allegiant Stadium next month.

The Kelces will be the first brothers to play against each other in a Super Bowl matchup after both of their teams won their respective conference championships on Sunday.

Both Jason and Travis have each previously won a Super Bowl, with Jason’s Eagles winning Super Bowl LII and Travis’ Chiefs winning Super Bowl LIV.

The Kelces will be the first pair of brothers to play against each other in a Super Bowl, however, won’t be the first on opposing sides. Baltimore Ravens head coach John Harbaugh defeated his brother, then-San Francisco 49ers head coach Jim Harbaugh, in Super Bowl XLVII.
