Travis Kelce got out of the house on Wednesday to hit up a concert … but it was NOT a date night for the NFL star — TMZ Sports has learned Taylor Swift stayed behind.The Chiefs tight end made his way over to the T-Mobile Center in Kansas City to catch Jelly Roll belt out some tunes to a packed arena … but we’re told Swift was not among those in attendance.

Unclear where she was — but with an “Eras” tour show slated to go down at Rogers Centre in Toronto on Thursday night … it’s safe to assume work took priority.The concert, nonetheless, seemed like a blast … and at one point during the action, Kelce got to snap a pic with Ernest — Jelly Roll’s opener — backstage.No word if Kelce’s BFF, Patrick Mahomes, tagged along with him … but the quarterback’s little brother, Jackson Mahomes, was there — filming himself grooving to the music in some sweet seats.Kelce almost assuredly called it a night early … Kansas City had practice Thursday morning — and the team is gearing up for a huge road game against the Bills on Sunday.As for Taylor, the Toronto shows are scheduled to go ’til next week, but there is a break in the action from Sunday to Wednesday … so a reunion — and maybe a date night raincheck?? — with TK could very well go down following the big tilt in Buffalo.
