The EFL have confirmed Grimsby have been fined £20,000 after they fielded an ineligible player during last weekend's shock Carabao Cup second-round win against Man Utd.

Half of that will be suspended until the end of the 2025/26 season.

The club submitted the registration of Clarke Oduor at 12.01 pm on the day before the fixture, one minute after the 12pm deadline.

Oduor came on as a second-half substitute and ended up missing his penalty in the shootout, which Grimsby won 12-11.

A statement said: "The club self-reported the breach upon discovery the day after the fixture had been completed.

"Following a comprehensive review of all the evidence and considering prior decisions taken in respect of offences in the League Cup, the board determined that the issuing of a fine followed precedent.

"The board further noted the club’s non-compliance was not deliberate with no intention to deceive or mislead. The club has since implemented several actions to prevent a similar occurrence in the future."
