Cyclist down, 27th and Guadalupe. Anyone have any information?

Does anybody know anything about the cyclist that went down at 27th and Guadalupe around 2:30am Saturday morning? I saw the aftermath from a distance and circled back around, but didn't see what happened to cause the crash, or manage to get the cyclists information as he was KO'd. The rider was a blonde guy with facial hair, riding a yellow fixed gear. According to an eyewitness the guy just lost traction and went down, but his head was bleeding and he was completely out of it so it looked not so good. After a few minutes the police showed up and began dealing with it so we boogied, but if anyone has any information about the guy let me know. Hope you're ok, dude.
