Up all night, presumably in a tremendous amount of pain/pain medication induced stupor, Kobe Bryant took to Twitter and Facebook to voice his frustration over thepotentially career ending achilles injury heard round the world. The emotional open letter after the jump.

Totally pissed at the Pats’ stunning elimination in the AFC title game, Wes Welker’s wife Anna Burns Welker took her rage out on Facebook. She took some sort of high road, chewing out Wes’s opponent, not his teammate, mocking Ray Lewis for being an alleged murderer.

This is probably my favorite piece of e-trash talk ever.

If you’re a pro sports franchise coming off a disappointing season, do yourself a favor: don’t post a message on Facebook thanking fans for their support during your “up-and-down” campaign.

You – you there! You are reading SportsGrid at this very moment. We thank you for that, and hope you are enjoying your stay. And if you are – did you know that your SportsGrid experience need not be limited to the confines of this site? No, there’s a whole social media world out there, and SportsGrid’s a part of it. Won’t you join us as we plug away in various corners of the internet? See where to find us after the jump.

The Panthers haven’t won a single coin toss this season, so they left it to their fans to decide on heads or tails for the coming week. Except it didn’t quite work out as planned.

When we last visited the Marlins’ official Facebook page, they were asking fans to share their favorite memories of the Marlins’ miserable failure of a 2012 season, and the fans were justifiably responding with venom. So what would they say now that their team has traded nearly every good player away?

Red Bull, which naturally sponsored the 24-mile skydive of Felix Baumgartner, congratulated him on the Red Bull Stratos Facebook page. But someone the didn’t give the message a meticulous enough proofread and, well, even though that delete button exists, the following screenshot was long since taken.
