The NHL-leading Ducks announced the deal with their former backup goalie Tuesday.
The 34-year-old Bryzgalov began his NHL career with Anaheim, appearing in 69 games from 2001-08. He was the backup to Jean-Sebastien Giguere on the Ducks' only Stanley Cup championship team in 2007.
Bryzgalov went on to play for Phoenix, Philadelphia, Edmonton and Minnesota. He appeared in 12 regular-season games and nine playoff games for the Wild last year.
Bryzgalov had been out of hockey this year until getting the call from the Ducks, who need a dependable backup behind Frederik Andersen. John Gibson, Anaheim's 21-year-old top prospect, hasn't played since Oct. 30 due to a groin injury.
