Rittich is expected to start at home against Edmonton on Thursday, per Andrew Gross of Newsday.
It will be Rittich's first start of the season, and his first as a member of the Islanders. He had a 16-14-2 record, 2.84 GAA and .886 save percentage in 34 regular-season appearances with the Kings last year. Rittich is serving as the Islanders' No. 2 goaltender, and he's unlikely to get many starts behind Ilya Sorokin.
