Amid the ongoing criticism of the implementation of VAR in the Premier League this season, a referee finally used the pitchside monitor to aide a decision on Sunday.
Referee Michael Oliver watched a replay of an incident between Crystal Palace's Luka Milivojevic and Tom Huddlestone of Derby County and overruled his original decision of a yellow card to send off the Eagles skipper midway through the second half.
One-time Palace loanee Chris Martin scored the only goal against his former club and it proved enough to dump Roy Hodgson's side out of the competition following a 1-0 defeat at Selhurst Park.
