It didn't take long for the Colorado Avalanche to leave their mark on the Stanley Cup -- and not in a good way -- 'cause the new NHL champions dented the iconic trophy just 5 minutes into their wild celebration!!
The Avs beat the Tampa Bay Lightning in six games to secure their third title in franchise history on Sunday ... beating the Bolts in a 2-1 contest.
The champs were rightfully pumped after securing the 'ship ... and star wing Nicolas Aubé-Kubel was a bit too pumped -- 'cause when it came time to take a group pic with Lord Stanley, the dude slipped up on the ice and dented the hardware in the process!
