I started to watch that game passively after the 2nd but what are the chances they were just being precautionary with the Pavs and Hertl injuries? I don't remember the score or the time remaining when either of them left the contest but it may have been more of a "f*** it, lets rest up and get ready for Tuesday" conversation between them and the trainers.
Karlsson is toast. Only way I want him in the lineup is as a 7th defenseman playing the PP, o-zone face-offs after Blues icing, as the extra attacker on delayed penalties, or a pulled goalie situation. I'd love the guy and would be clamoring to have him back if he didn't try to be a hero with these injuries. Him trying to play through it has hurt the Sharks much more than him sitting and getting full treatment. I'm just bitter about his stint here at this point.
