Egorov had previously defeated Russo twice in APB, and claimed his third triumph after the two-time AIBA World Champion was forced to pull out of the bout at the beginning of the sixth round following an injury to his midsection.
Russo came out to the ring to the sounds of Madonna, and proceeded to use swift footwork, solid left hands and immaculate timing to win the first round on two scorecards.
Both men had success with hooks throughout the opening rounds, but it was always Egorov who was getting the better of the exchanges.
His power stunned Russo on several occasions, and he won the fourth and fifth rounds across the board to the delight of the loud audience in Moscow.
The bell had barely rung in the sixth round before Russo was examined by Dr Thorsten Dolla at ringside, and a decision was made to remove the Italian from the contest as a result of his injury.
