Harry said after the game:
"I just questioned the referee's overall performance which I thought was inept.
"Every game I see this season has seven or eight bookings. I think it's frightening - if you have that many bookings you would think it had been a war.
"If it carries on like this we're going to end up with no squad in a month's time because they will all be suspended."
Wolves boss Dave Jones refused to comment on a specific incident but did say "I thought the referee made a few strange decisions".
