Burnley were saved from a costly FA Cup mistake when they named a suspended player in their line-up - as opponents Bournemouth pointed out the error.
Left-back Erik Pieters was picked for the match at Turf Moor - but the visitors noticed he was ineligible after being booked against MK Dons and Fulham in the previous two rounds.
"It was just a simple admin error," Clarets boss Sean Dyche said.
Anthony Glennon was drafted in instead as Bournemouth won 2-0.
Since 2018, yellow cards in English domestic professional football have only counted towards suspensions in the competition in which they are received. Pieters was banned for collecting two bookings in this season's FA Cup.
Dyche said he was made aware of Pieters' ineligibility by a Bournemouth staff member.
"The rules have changed this year with the booking situation and the number of games in the FA Cup. It was just a clear oversight," he added.
"To be fair to Bournemouth, they flagged it and mentioned it, so credit to them for a bit of gentlemanly conduct.
"We jumped on it straight away and people at our club held their hands up in the right slots."
