"For the first goal, in my opinion, and probably 25,000 people in the stadium the player was five yards offside," said Adkins, who was sent to the stands after contesting the decision.
"The linesman was closer to me than being up with play. He did not give the offside and that was very disappointing.
"I have then gone and stood five yards outside the technical area, not sworn or used any abusive language, and the referee and the fourth official have come over and asked me to go and sit in the stand.
"As for the sending off, I had a super view in the stand of the players colliding. I could clearly see the referee signal the players had collided and then the linesman, with his new Christmas present, put his flag up and then the referee came over.
"To be a red card was really damaging for us because it was going to be hard enough as it was against a top team with 11 men let alone 10.
"But let's not take anything away from West Brom. They will be a Premier League team next season and it is a great experience for me and my team to play against them."
Baggies manager Tony Mowbray admitted the Iron had made life difficult for his table-topping side in the early stages.
"Early on this game was tight. It is a tactical battle as well as a physical confrontation," he said.
"The longer it goes on and spreads out it becomes more of a football match.
"They played a shape that had potential to cause us problems but unfortunately that went out of the window after the sending off. That allowed us to get a hold of the game."
