The woman got onto the grass at The Hawthorns before kicking the ball at the man, who then took her off by the arm as she fell over and had to be picked up again.
Play in the Black Country FA Cup derby between West Brom and Wolves at The Hawthorns was suspended for more than half an hour after trouble flared in the stands and fans spilled onto the pitch.
Police later confirmed that five arrests were made for public order offences, while another man was arrested outside of the ground before kick-off for possession of an offensive weapon .
