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.
Just the feel for the direction they were headed and what they're trying to do, it just felt that this is a really good thing for this organization. They've got the pieces. We can put something together and go on a run or two and be together for a while, and I'm really excited about that opportunity. The team we have here has an opportunity to win, and that's the most attractive thing.
