Grimsby Town have completed the deadline day loan signing of Fin Cartwright from Middlesbrough on a season-long deal. The 19-year-old midfielder will join David Artell's squad for the 2026/27 campaign and link up with the team at Blundell Park.
Where does Fin Cartwright fit in Grimsby Town's plans?
Cartwright, born in Redcar, came through Middlesbrough's academy after joining at Under-7 level. He made his senior debut for the Teessiders in August 2023, coming off the bench in a 3-2 Carabao Cup win over Huddersfield Town at just 16 years and 161 days old. That appearance made him the second-youngest player to represent Middlesbrough in a competitive fixture. During the 2025/26 season, he was a regular for Middlesbrough's Under-21 side, making 12 Premier League 2 starts and contributing two assists.
What experience does Cartwright bring to Blundell Park?
The young midfielder has also represented England at youth level, earning nine caps across the Under-16 and Under-17 teams. His loan move to Grimsby Town comes as the Mariners sit 11th in League Two with 6 points from 4 games, recording a recent form of DDDW. Grimsby have scored 5 goals and conceded 4 this season, leaving them just 3 points behind league leaders Bristol Rovers. For more on the team's current position, see the standings.

Head Coach David Artell added: "Fin is a really exciting young player and we’re delighted to bring him in." The signing was confirmed by Grimsby Town Football Club as the latest addition to their squad ahead of the new season.
