Usman revealed how he helped Hendricks prepare for his fight with St. Pierre

"I actually studied George a lot even before I was just thinking about signing in the UFC. I had to study him because I was invited to Johnny Hendricks' training camp. I had the fate of being his main sparring partner. I was invited to emulate George. My goal was to do everything in my power to help Johnny, so I had to watch you closely. It didn't matter what George's level was, Johny Hendricks is a fighting champion, but I had an understanding that you were going to step up and do whatever it took to beat him," MMA Fighting quoted Usman as saying.
