"Saturday at half-time was the angriest I have been this season," Davies revealed of his altercation with Davis, who is definitely out of the West Ham fixture.
"But I picked the wrong man, he was 6ft 4ins and I was two foot six.
"He was coming off at half-time and I was angry because I felt the change would cost us the game and had been a huge dent for us.
"There were words, I said a few things and I tried to grab him by the throat but he was too high!
"We had played so well for 45 minutes we could have done without the disruption. We had looked solid as a team and losing him was a big, big loss which unfortunately happened, so I lost the plot."
