The 26-year-old centre-back Lewis Mayo, who most recently played for Kilmarnock FC, will officially became a Dons player ahead of the 2026/27 season, adding leadership and versatility to the Club’s defensive unit.
Lewis, who established himself as one of the Scottish Premiership’s most consistent defenders during his time at Rugby Park, is known for his strong defensive instincts and significant pace, and had been a key figure in Kilmarnock’s backline.
He agreed a three-year deal to join Aberdeen when his contract expired at Kilmarnock.
