Play at the Hawthorns was suspended after 82 minutes when fans began to spill onto the pitch, with it believed a number of Wolves fans had made their way into the home end, causing fights to break out.
Wolves were 2-0 up at the time thanks to goals from Matheus Cunha and Pedro Neto, but it was unknown whether play would resume.
The game would end up restarting from the 77th minute after a period of stoppage, with the score staying the same for the remainder of the contest to see Gary O'Neil's side progress.
However, the delay meant the contest ate into time allocated for the FA Cup fifth round draw, which was due to take place at 2:10pm GMT - 20 minutes before Liverpool's game against Norwich kicked off.
It's now been decided that the draw will take place at half-time of the Reds contest, with the FA Cup's YouTube channel showing it scheduled for 3:15pm GMT.
Ball number 10 has been awarded for the winner of Liverpool or Norwich.
