In 1990, the All-Ireland final saw Cork’s hurlers facing Galway once again, marking their second encounter in four years. McCarthy, positioned at midfield, confronted a formidable Galway team that swiftly established a seven-point lead, living up to their favored status. Undeterred, Cork mounted a remarkable comeback, spurred on by the contributions of players like Tomás Mulcahy. The result was a thrilling high-scoring game, culminating in Cork’s victory with an impressive scoreline of 5–15 to 2–21. This triumph secured McCarthy’s second All-Ireland hurling medal.

Merely two weeks later, McCarthy returned to the hallowed grounds of Croke Park for the All-Ireland football final. Squaring off against perennial rivals Meath in their third meeting in four years, Cork found themselves in another closely contested battle. Despite the dismissal of Colm O’Neill, reducing Cork to fourteen men, McCarthy played a pivotal role in steering his team to victory with a narrow 0–11 to 0–9 scoreline. This historic achievement cemented McCarthy’s legacy, as he became the inaugural and, as of 2023, the sole player to achieve the extraordinary feat of winning All-Ireland football and hurling medals in the same season, forever etching his name into the storied pages of GAA history.

In a heartfelt tribute to the late Teddy McCarthy, Cork GAA has organized the Teddy McCarthy Tribute Night scheduled for December 9th. This poignant evening will honor Teddy’s enduring legacy, with both Cork Footballers facing Meath and Cork Hurlers taking on Galway. These two significant games serve as a respectful nod to the teams Teddy played against in the All-Ireland finals of 1990. The event not only commemorates a Cork GAA icon but also unites fans in celebrating Teddy’s contributions to both football and hurling, creating a fitting and memorable tribute night in his honor.
