During Game 3 of the Western Conference Final in the 2005–06 playoffs, Petersen scored his first ever NHL playoff goal against
Ilya Bryzgalov of the
Anaheim Ducks by stealing the puck and wrapping it into an empty net while Bryzgalov attempted to make a play behind his goal line. In 2008 Petersen had a memorable experience at the
AHL All-Star Game. The experience began the day before the game when Petersen won the 2008 AHL Skills Competition's fastest skater event with a 14.001 second lap. The experience continued during the game as Petersen recorded 3 points including scoring on the first ever penalty shot in an AHL All-Star Game. In the
2013–14 season, his seventh within the Stars organization, Petersen helped the Texas Stars to claim their first
Calder Cup and immediately announced his retirement from professional hockey. == Coaching career ==
