West Brom’s FA Cup defeat at home by local rivals Wolves was suspended for 38 minutes on Sunday because of fan disorder at The Hawthorns.
Trouble flared after Premier League Wolves went 2-0 up on 78 minutes.
Missiles were thrown at one end of the pitch and a large fight broke out in a corner at the other end.
Fans spilled on to the pitch and the players were taken to the changing rooms as police restored order, before returning to complete the game.
Matheus Cunha had doubled Wolves’ lead, adding to Pedro Neto’s first-half opener.
The players returned to the field shortly after 13:50 GMT to begin a warm-up, before resuming the game 10 minutes later.
There were no further goals as Wolves clinched a place in the fifth round.
