Petersen will guard the home goal Saturday versus the Senators, Jared Shafran of the Kings' official site reports.
Petersen backed up Jonathan Quick in the last two games, but Quick was shelled for six goals by the Maple Leafs on Wednesday. This will give Petersen a chance to get back to a more even share, and he'll face a Senators team that has been shut out in three of its last six games.
