Liverpool have been fined $246,000 for fielding an ineligible player in the League Cup third round clash at MK Dons last week.
Half of that fine will be suspended until the end of next season, say the English Football League.
Jurgen Klopp brought Spanish midfielder Pedro Chirivella, 22, off the bench in the 2-0 win at MK Dons, but he did not have international clearance to play after returning from a loan spell at Extremadura in 2018-19.
Chirivella had not played for Liverpool for over three years before coming on against MK Dons, and Liverpool had previously admitted a potential administrative error over his international transfer certificate (ITC).
There were fears that Liverpool may be kicked out of the competition but they will now face Arsenal in the last 16 at Anfield on Oct. 29.
