The Tampa Bay Lightning had lost only once this season when carrying the lead into the third period - until tonight.
The Lightning were up 2-1 on the Columbus Blue Jackets at the end 40 minutes, but wound up on the wrong end of a 3-2 decision on Monday night.
Mark Letestu was credited with the winning goal on a deflection with 2:38 remaining in regulation time. U.S. Olympic hockey team snub Jack Johnson earned a helper on the goal, which he was originally credited with.
Columbus forward Nathan Horton scored his 200th career NHL goal with a wicked wrist shot early in the third period to tie the game.
