Brewer was injured while blocking a shot in just his second game with the Ducks, who acquired the 35-year-old veteran from Tampa Bay in a trade last Friday.
Brewer has four assists in 19 games for the Lightning and Ducks this season.
Although Brewer was out when the Ducks hosted Philadelphia on Wednesday night, defensemen Clayton Stoner and Mark Fistric were activated from injured reserve. Stoner was back in the lineup against the Flyers after missing five games with mumps.
Anaheim also recalled forward Chris Wagner from the AHL.
