Hull FC coach Lee Radford criticised his players’ attitudes following their defeat to St Helens.
The Airlie Birds went down to a 32-18 defeat to the Saints at the KCOM Stadium on Sunday.
Hull were 6-2 ahead at the break but had little response to Saints’ second half blitz, where they posted 30 points on the board.
Radford said: “We put the ball out on the full and I was really disappointed with the response of some of the players after that.
“We turned into a team of officials rather than players. When you put all your focus on getting a referee to change his decisions that is what happens.
“We knew we had to play for 80 (minutes) and we played for 40. If you respond like we did to a bit of adversity you get beaten.”
