Defenceman Patrick Sieloff will not be returning to the Windsor Spitfires this season.

Spits general manager Warren Rychel announced Sieloff will instead begin his professional career with the Calgary Flames organization.

“We're proud of Pat's accomplishments and to see yet another one of our players moving on to a professional career,” Rychel said. “Pat was a true Spitfire, both on and off the ice. He was a big part of our team and will be missed. He will have a long career in the NHL and we wish him all the best.”

The 19-year-old played 45 games with the Spitfires last season, after completing two years with the United States National Development Team.
