Slightly overstretched my knee during a cool-down stretch two weeks ago. Power through it or wait until it's no longer sore?

I was doing the "reclining hero" pose in the Starting Stretching guide and I think I was a little too ambitious with it and my knee started to hurt the next day. It's nothing super painful, just a dull ache. Leg day is coming up (complete with squats, leg press and all of that fun stuff) and I am wondering whether I should just skip leg day until the soreness is completely gone or just work out anyway? This might seem like a dumb question, but I've been told some surprising information in the past and I want some opinions on it.

Thanks!
