Artur Is a Russian Name, Which Means “Bear-Like”​

[SouthpawRight]

What a most fitting name. Who needs a nickname when one’s name fits perfectly

Alvarez brands himself a bear too. See tshirt in most recent fight

Biv the bear slayer

I believe that Artur is of Celtic origin which was then adopted by Romans and spread throughout Europe to include Slavic regions It is associated with words such as "bear, "eagle" or "strong man". All apropos for Beterbiev.
