It's one of the things I hate the most about being a fan of NFL teams, just one or two key injuries can be the entire season. It's pretty devastating to lose Urlacher, he is the heart of that defense which was playing great last night minus the TD pass (that was just a gutsy call by Green Bay, I mean who goes deep on 3rd and 1 on what could be your final possession?).
And I never "LOL" when other teams have season ending injuries (with exception to tom brady), I don't find that shit funny at all even if it's a rival team. I LOL when a team gets embarrassed or their asses kicked, but injuries nah cuz that shit can happen to anyone at any given time.
