Chris Jones -- All-Pro defensive lineman, Super Bowl champion ... and Taylor Swift cover band??
Pretty much ... 'cause Travis Kelce's teammate briefly showed off his pipes by singing "The Fate of Ophelia" in front of a bunch of reporters at Thursday's press conference!!
The silly moment went down as the 31-year-old made his way to the microphone at the practice facility ... with the song bumping on his phone as he nodded his head.
Jones screeched out some high notes as he recited Swift's "Keep it one hundred on the land, the sea, the sky" lyric .
