Dober was unranked when he fought Islam.
“Drew Dober enters this fight riding a four-fight winning streak. He’s won three in a row, all by stoppage. […] Though
unranked, he’s a win or two from a spot in the top ten. A victory over the 14th ranked Makhachev will certainly boost him up the lightweight ladder.
Dober can stop you with either hand, however, if he has an Achilles heel, it’s he can be submitted. He’s been tapped out on a number of occasions.”

“In Makhachev’s way is Dober, who is 6-1 in his past seven outings. […]
Currently unranked in the top-15, a win over Makhachev would give the argument he needs to face more esteemed opposition.”
