The Senators say Anderson accidentally cut his right hand while preparing a meal Thursday. He was treated at the hospital and is expected to make a full recovery.
The 30-year-old Anderson has appeared in 56 games this season, posting a 2.85 goals-against average and 29-19-6 record. The Senators host the Boston Bruins on Saturday before the New York Islanders come to town Sunday.
Last month, L.A. Kings forward Dustin Penner sat out a game after suffering back spasms while eating pancakes.
In baseball, former Toronto Blue Jays reliever Brian Tallet missed 10 weeks last season after hurting his ribcage following a hard sneeze.
