Richards will miss Friday's game in Buffalo following the passing of his grandfather, Ansar Khan of MLive.com reports.

EDGE Analysis

Khan adds that Richards will play Saturday against the Ducks, a home game that precedes three straight games on the road. It's not clear who will take his spot in the lineup Friday, but it appears that a call-up will be made since there are only 11 forwards available and currently no extra defensemen that could temporarily assume a forward role.
