Was Dana White mad that Lesnar lost or was he mad because supposedly Lesnar yelled Stop to stop the fight?

I notice Dana did not have his usual smile when he put the belt around the winner. In fact he looked a bit annoyed about something. I must have watched that fight 17 or 18 times and I never notice Lesnar yelling the fight to stop because I was to focus on the beat down he was getting. So what are your thoughts on Dana's reaction to Lesnars lost.
