The Rangers have placed backup goaltender Stephen Valiquette on waivers and have claimed seventh-year center Erik Christensen off waivers from Anaheim.

Teams have 24 hours to claim Valiquette, who has spent the past four seasons with the Rangers, but has struggled with a 3.74 GAA in six games this season.

Christensen appeared in nine games for the Ducks this season without recording a point, but will receive “an opportunity,” as expressed by coach John Tortorella, as Brandon Dubinsky recovers from a broken hand.

The Rangers will call up 23-year-old goaltender Chad Johnson, whom the Rangers received from the Penguins this summer in exchange for a fifth-round pick. Johnson has played 18 games for Hartford (AHL) this season, compiling a 10-6-1 record with three shutouts, a 2.10 goals against average, and a .926 save percentage.

Tortorella also announced an unspecified injury to Donald Brashear.
