TORONTO -- Curtis Joseph, fourth all-time in wins by a goaltender, will announce his retirement at a news conference Tuesday at the Air Canada Center in Toronto, a source told ESPN.com on Saturday.

The 42-year-old Joseph last played last season with the Toronto Maple Leafs, backing up Vesa Toskala.

Joseph's 454 career regular-season victories trail only Martin Brodeur, Patrick Roy and Ed Belfour all-time. Joseph played 958 regular-season games over 19 NHL seasons with St. Louis, Edmonton, Toronto, Detroit, Phoenix and Calgary.

He also appeared in 133 playoff games, reaching the conference finals twice with Toronto in 1999 and 2002.
