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's such a privilege to be one of these 80 great players to do this milestone, and it doesn't get better than this doing it where I started. It means a lot to me. A big thanks goes to all the players tonight who helped me to achieve that and also all the players through my career.
