Travis Kelce and Chiefs Kingdom won't like this ...
An extremely talented Baltimore fan is hoping to bring some good Taylor Swift juju to his favorite team ... by painting a mural of the pop star decked out in a Lamar Jackson jersey!!
The artist goes by dlordink on social media ... and at some point after it was revealed the Ravens would take on the Chiefs in the AFC Championship Game this weekend, he got the idea to try to use Swift's good luck powers for his squad.
