Kellie Harrington will come home with silver after suffering defeat to Finland's Mira Potkonen in the Strandja multi-nation boxing tournament in Sofia on Saturday. 

Harrington, the 2018 world champion, lost the 50kg final to Potkonen on a split decision, the Finn enjoying the better of the third and final round of a closely fought contest. 

The 39-year-old Potkonen, current European champion, is best known to Irish boxing fans as the conqueror of Katie Taylor in the bronze medal fight at the Rio Olympics in 2016.

Potkonen is enjoying a winning streak against Irish boxers. Before today, she defeated Harrington in the 2017 EU Championship and beat her in the last four of the 2018 European Elites.

The Finn also beat Dundalk's Amy Broadhurst in the bronze medal fight earlier this week. 

Despite today's loss for Harrington, it was a positive week for the Irish boxers, the tournament itself serving as a warm-up for the Olympic qualifiers which take place in London in March. 

Harrington, back in action after a seven-month absence with a thumb injury, won three bouts en route to the decider setting up today's fight with victory over Bulgaria's Denicia Eliseeva on Friday. 

In addition to her silver, Roscommon middleweight Aoife O'Rourke took bronze following her victory over Brazil's Flavia Figuerdo on Thursday before falling to America's Naomi Graham the next day.
