Rittich is set to guard the home goal against Ottawa on Saturday, according to Zach Dooley of the Kings' official site.
Rittich has an 8-6-0 record, 2.52 GAA and .886 save percentage in 15 appearances this season. He limited the competition to one goal in four of five starts from Nov. 16-27, but there was a disastrous 7-2 loss to San Jose during that stretch, where he stopped just 14 of 21 shots. The Senators rank 14th in the league with 3.18 goals per game.
