Hibernian have signed Northern Irish full-back Sofie Keenan from NIFL Premiership side Glentoran on a two-year deal for an undisclosed fee. The 20-year-old joined Glentoran from fellow Northern Irish side Linfield back in January 2024 and made over 70 appearances in the country's top flight and turned out in the Champions League. The full-back played a key role in Glentoran's title win in 2025 and was named young player of the year during that campaign.
