Having suffered from intense pregame nerves just 30 minutes before the kickoff of Super Bowl 50, Denver Broncos quarterback Peyton Manning confirmed Sunday that he felt much better after throwing up blood in the locker room. I always get major butterflies right before a big game, so its nice to just get it out of my system, Manning said while wiping smeared blood from around his mouth with a paper towel, having spent over 20 minutes vomiting blood into a toilet until he was left dry-heaving. Its good to be nervous, though. This has just become part of my routine over the last few years. Manning added that he also likes to spend a few minutes hitting a punching bag before each game in order to pump himself up and get the feeling in his arms back.
