A representative from Bournemouth saved Burnley by telling them that they had put the ineligible Erik Pieters in their starting line-up prior to Tuesday's FA Cup fifth-round clash, Clarets manager Sean Dyche said.
Pieters had picked up bookings in the previous two rounds of the competition, meaning he was suspended for the game against the Championship side.
The Dutchman was replaced before kick-off by Anthony Glennon, with the Cherries going on to win the game 2-0 and advance to the quarter-finals.
