Overview
- Grimsby registered Clarke Oduor at 12:01 pm the day before the tie, missing the EFL deadline by one minute.
- The EFL imposed a £20,000 sanction, with £10,000 suspended until the end of 2025/26, triggered by any further ineligible‑player breach.
- Grimsby said a computer problem delayed detection, accepted the punishment and tightened internal processes.
- Manchester United’s elimination remains in place, and the club is understood not to be appealing the decision.
- League Cup practice favors fines in such cases, contrasting with FA Cup expulsions in past examples; Grimsby next face Sheffield Wednesday in round three.
