Johnson Left Feeling Angry Over Late Strike
From a drop ball situation in their own half, Wolves booted the ball into the City half of the field and out for a throw in.
That throw in led to a free kick for Wolves and upon taking that, Matt Doherty headed home to win the game late on for Wolves.
Johnson was not pleased with what he called 'unsporting behaviour.'
Johnson told BBC Radio Bristol: 'I'm an angry man at the moment if I'm honest, for a number of reasons.
'A big club like this, you don't expect a historic club to have to resort to unsporting behaviour.
'The lad said he was going to kick it back to the goalkeeper and he smashes it out right in our corner and puts us under pressure.'
Wolves boss Kenny Jackett also had his say on the incident, and he saw nothing wrong, he said: 'He (Johnson) was unhappy on the sidelines definitely. I wasn't quite sure what the expectation was.
'The ball went out for a throw-in quite deep. It is splitting hairs really.'
After the game City ended up in 20th place in the league, just two points away from the drop zone.
