Apparently he got an awful gash in his leg while hitting the fresh powder. Luckily, his beautiful partner-in-crime Paris was there to help/take pictures! (Okay, mostly take pics! Ha!)
Here's what she said on her Pheed:
Such a scary day on the slopes today. After seeing the gash on @RiverViiperi's leg, I almost passed out. I have never seen a cut that deep in my life. He is so brave, I can't even imagine the pain he went through today. :(
And then she posted the pic of him (above) getting help, while she lounges in the foreground!
Those weren't all the pics she took either, and if you have a weak stomach, you might want to look away! It looks PAINFUL!
We're so glad you're okay, River! Take it easy, and maybe come down from the mountains for a while!!
