VIDEO: Karlsson blows a tire, Letang scores

This wasn't the start the Ottawa Senators were hoping for coming out of the All-Star break.

Already down a goal to the Pittsburgh Penguins, captain Erik Karlsson wiped out at the opposing blue line, giving up a Chris Kunitz breakaway. Craig Anderson was able to stop Kunitz, but Karlsson couldn't get back quick enough to catch defenseman Kris Letang, who buried a feed from Sidney Crosby.

Kunitz added a goal later in the first period, which ended with the Penguins leading 3-2.
