West Brom’s FA Cup tie at home to local rivals Wolves was suspended on Sunday because of fan disorder in the 82nd minute.
Trouble flared after Premier League Wolves went 2-0 up at the Championship side.
Missiles were thrown at one end of the pitch and a large fight broke out in a corner at the other end of West Brom’s Hawthorns ground.
Fans spilled on to the pitch and police have been called in to restore order.
