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.
There's not much to say. We played like [garbage]. I think every guy in the room should be completely embarrassed about how they played tonight. Every single person. To start a road trip, one of the biggest road trips and have a division rival chasing you down and have a ton on the line, it's ridiculous how we played tonight.
