UFC 191 was a pay-per-view event for the UFC. UFC 191 was headlined by Demetrious Johnson. Therefore, it’s like that UFC 191 did not do so well on pay-per-view.
Now, no one (read: Dave Meltzer) has released any numbers, but it’s not too hard to predict these things with Demetrious Johnson. His last three fights – all in PPV headlining spots – have done 125k, 205k, and 115k in reverse chronological order. The show pulled in $1.36 million at the gate, worst among UFC PPV events at the MGM Grand Garden Arena this year, less than half of what the next-worst UFC PPV did at the MGM Grand Garden Arena this year, and the lowest gate for a UFC PPV since UFC 49 back in August 2004.
