In the month since his submission victory over Sam Stout at UFC 161 in Winnipeg, James Krause has had plenty of time to think about what substances may or may not have been floating around his system. “You just start thinking about everything,” Krause told MMAjunkie.com (www.mmajunkie.com). “Every little thing runs through your mind, like, ‘What did I have, what did I eat?’” And yeah, that’s about what it feels like when you have a very important drug test to pass. Even when you know you haven’t used any banned substances – even when you are absolutely sure that there’s no valid reason why your test shouldn’t come back clean – it’s hard not to stress about it when there’s $100,000 on the line, as there was for Krause after he netted dual $50,000 bonuses for “Fight of the Night” and “Submission of the Night” at UFC 161 on June 15.
