Russian Denis Shafikov retained his European light-welterweight title, after Scotland's Lee McAllister was forced to retire after seven rounds with a hand injury.
Underdog McAllister made a solid start in the opening round but the champion soon began to dominate the contest, defying his seven-inch height disadvantage to land with regularity.
Roared on by a home crowd in Aberdeen, the Scot battled through the punishment for seven difficult rounds before finally accepting defeat.
Speaking to Sky Sports 1 after the fight, McAllister said: "I never seem to get a fair crack but things happen for a reason.
"I hurt my left hand, hit him on the top of the head, I thought I was boxing ok to be honest but once I lost my jab.
"I was a bit knackered. Every time I hit the jab, I had shooting pains up my arm but there's no excuses, he came in here and did a job."
Shafikov remains undefeated in 29 fights.
