Travis and Jason Kelce took a break from their usual lighthearted banter to weigh in on the tragic Kansas City shooting this week ... thanking the first responders for springing into action and vowing to help those affected.
The two NFL brothers dropped a surprise video ahead of Wednesday's "New Heights" podcast episode ... with Travis explaining it "didn't feel right" to move forward with the pre-taped show without first addressing the incident after the Chiefs' Super Bowl parade on Feb. 14 that left one dead and more than 20 others injured.
