Headlining a card tomorrow in Antonyan's hometown of Barnaul in Siberia, with eight rounds scheduled at light heavyweight. The co-main event will feature Leon's slightly younger & smaller brother in a 6-rounder at super middleweight - and Vladimir Antonovich Antonyan vs. Makhmud Anvarbegovich Musalov might actually be the better and more interesting fight. Elder brother Leon is facing, on paper, the biggest name of his career (Piternov was a touted domestic prospect once upon a time, capturing the Russian national super middleweight title a decade ago, defending it once, then capturing the light heavyweight version in 2015...but immediately thereafter ran smack into the young & hungry Dmitry Bivol, coming fresh off his pro debut. Bivol smashed Piternov up and sent him into a tailspin of ruination, with the Cossack going just 3-16 in the four years since....) although it arguably is a big step-down in h2h terms from Uzbek southpaw Mirzoxidjon Shuxratbek Ogli Abdullayev, versus whom Antonyan fought to a draw last year. Vladimir would appear to have a tougher assignment in the 4-0 Musalov, who knocked out Gasan Khaibulaevich Gasanov in just his third pro bout...although Musalov would then disappear off the face of earth and for some reason hasn't fought since 2015.
