Both sets of players left the pitch after trouble between fans at the third round FA Cup clash between rivals West Brom and Wolves on Sunday.
The disorder erupted after Gary O'Neil's Wanderers took a two goal lead at The Hawthorns.
Missiles were launched and a large fight broke out in one corner of the stadium - fans subsequently spilling on to the pitch.
The police were called in to restore order and arrests have already been made.
Matheus Cunha had doubled Wolves' lead to spark the trouble on the terraces, the Brazilian's strike adding to Pedro Neto's first-half opener for the visitors.
The players returned to the field shortly after 13:50 and the game resumed 10 minutes later after a short warm-up for both teams.
