The Ducks recalled goalie John Gibson from minor-league Norfolk, Va., and he practiced with the team at its morning skate.
"We're hoping [Bryzgalov] plays like he did in Washington," Boudreau said of Bryzgalov's 32-save showing in a shootout loss Friday. "If he does that, that's the Bryz we've seen …. "
Andersen, with 29 wins, was conked on the back of the upper neck in the third period Sunday when the goal was flipped over, the crossbar striking him and causing to fall face-first to the ice.
The pain hasn't subsided. Andersen received treatment Tuesday morning, and declined to speak to reporters. By being placed on injured reserve, he'll be sidelined through Sunday's home game against Washington, leaving him eligible for the Ducks' Feb. 18 home game against Tampa Bay.
"Last night, we made the decision it's better to be safe than sorry," Boudreau said.
Although Gibson, 21, emerged last season to win two playoff games and make the Ducks' opening-night start in Pittsburgh this season, his subsequent groin injury was followed by Andersen's run of 20 consecutive games and the team's decision to let Gibson get steady work in Norfolk.
In December, the Ducks signed Bryzgalov.
"Bryz is our second goalie right now … coming off his best game … Gibby's the guy in Norfolk right now," Boudreau said. "I think it would be a kick in the butt if all of a sudden we're throwing the youngster in. [Bryzgalov] has a chance to prove himself again and end the stigma of what happened the first three-four times he started."
Boudreau said it would be "great" if he could get Gibson a start either Thursday in Carolina or Sunday.
"We take it 24 hours at a time, wake up from tonight's game and try to make adjustments to see what we'll do in Carolina," Boudreau said.

Each was classified as game-time decisions by Boudreau, but it would be surprising to see either play Tuesdaynight.
