Source: Auld signs with Canadiens

The Montreal Canadiens have signed goalie Alex Auld to a one-year deal worth $1 million, a source said.

Auld was an unrestricted free agent. He will back up Carey Price in Montreal, as the Canadiens traded playoff hero Jaroslav Halak to St. Louis.

Auld has a 2.78 goals-against average and .904 save percentage in 207 career NHL games.

The Canadiens also re-signed Curtis Sanford to a two-way contract. Sanford, 30, likely will play in AHL Hamilton, and would earn $550,000 in the NHL.
