DeBoer told the media Wednesday that he informed general manager Lou Lamoriello that Johan Hedberg would start against the Sabres. He also told The (Newark) Star-Ledger that Brodeur, who was placed on injured reserve Feb. 26 (retroactive to Feb. 24), is feeling better but not close to returning.
DeBoer said Brodeur is no longer day-to-day.
