The hit on Richards occurred in the final minutes of the Kings' 2-1 loss on Saturday. Los Angeles coach Darryl Sutter said earlier Sunday that Richards was "fine" and the hit by Bolland was "not an issue," but Richards was scratched from the Game 2 lineup. His injury was then announced in the press box.
Richards has two goals and eight assists for a team-high 10 playoff points.
Defenceman Jake Muzzin also was scratched Sunday after he played in each of Los Angeles' first 14 playoff games.
It is really special. I had a lot of friends and family here tonight, and for my first [NHL] game in here it was great. I played here as an elementary-school player in the city championships and this was my first time back. It was a lot of fun.
