Hull City boss Phil Brown revealed after the loss to Aston Villa that he was unhappy with referee Steve Bennett's decision to overturn a penalty late in the game.
"People will end up talking about the penalty decision which wasn't," said Brown at the post-match press conference.
"It's beyond me whether it was a penalty or it wasn't - he's given it.
"A referee gives a penalty and then a linesman tells you it's not.
"Some days you get bad days at the office because of referees, other days you get bad days at the office because of players.
"Today was a good day at the office from the players and not so good from the ref."
