[1] Petiot made his professional debut in the 2005–06 season, playing mostly with Kings affiliate, the Manchester Monarchs.
Petiot spent the next two injury-plagued seasons with the Monarchs before signing as a free agent for the Toronto Maple Leafs on July 15, 2008.
[2] In the 2008–09 season, the Leafs assigned Petiot to their affiliate, the Toronto Marlies, then traded him to the Tampa Bay Lightning for Olaf Kolzig, Andy Rogers, Jamie Heward and a fourth round selection on March 4, 2009.
[5] During the 2010–11 season, Petiot was called up from the Oklahoma City Barons to replace an injured Theo Peckham on March 1, 2011.
With the NHL lockout affecting his status as a free agent, Petiot waited until the conclusion of the dispute before signing to a professional try-out contract with the St. John's IceCaps of the AHL on January 9, 2013.
