Jason Kelce missed every bit of Usher's halftime show on Sunday ... saying the chaos surrounding Taylor Swift during the break in the Super Bowl's action forced him to find cover elsewhere.
Travis Kelce's big brother made the revelation on Wednesday's episode of "New Heights" ... explaining so many celebs tried to get to Swift at half of the Chiefs vs. 49ers game at Allegiant Stadium, that he simply could not catch "a lick" of Usher's big performance.
