The move was made Thursday before the Wild's final exhibition game against Buffalo. Porter signed a one-year, two-way contract with the Flyers but was one of their final training camp cuts. The native of Toronto has played in 173 NHL games, all with St. Louis over parts of the past six seasons. Porter played in three playoff games for the Blues last spring in the Western Conference quarterfinals against the Wild.
The 31-year-old Porter was a teammate of Wild star Zach Parise at Shattuck-St. Mary's prep school in Faribault, Minnesota, and in college with North Dakota. Porter and Parise attended each other's weddings.
