Ward sustained a lower-body injury when he kicked out his right leg in an attempt to stop a shot by Mikael Granlund that went wide. Ward has been placed on injured reserve and is expected to miss 3-4 weeks.
Peters, who stopped 19 of 21 shots Thursday, had been recalled from the Charlotte Checkers of the American Hockey League on Oct. 14 after backup goalie Anton Khudobin sustained a lower-body injury in an Oct. 13 game against the Phoenix Coyotes.
The Hurricanes called up Mike Murphy from Charlotte on an emergency basis Friday to dress as Peters' backup against the Avalanche. A sixth-round pick (No. 165) in the 2008 NHL Draft, Murphy is 1-2-0 with a 3.81 goals-against average in three AHL games this season.
