OK EssJay, here's what I've come up with. I'm sure I missed a couple.
Jan. 15 Colorado _ Bortuzzo (concussion) leaves early 1st period.
Jan. 26, Vegas _ Bozak (upper body) leaves in second period.
Feb 6, Ariz. _ Thomas (thumb), leaves in 1st period.
Feb. 12, Ariz._ Sundqvist leaves w/3:49 left after crashing into boards
Feb. 18, S. Jose _ Barbashev (ankle) leaves early third period
Feb. 22 LA _ Gunnarsson (knee) leaves in 2nd period.
Feb. 24, LA _ Scandella (puck to face) leaves early third period.
Feb. 27 S. Jose _ de la Rose (lower body) leaves after two shifts
Don't have the game marked in my notes but Krug left in third period (upper-body) I think it was Feb. 15 vs. Ariz
