Police still want to speak to 19 men after disorder broke out at the West Bromwich Albion and Wolves match in January.
Last week, West Midlands Police released images of 25 men they wanted to speak to and since then six men have been identified.
Officers said they will be "spoken to in due course" as part of their ongoing enquiries.
Detective Chief Inspector Chris Fox from Sandwell Police said: "We have been making good progress with identifying individuals we want to speak to as part of our investigation.
"However, we still need your help to contact several people and I’d urge anyone who knows them to come forward and give us their names.
"We won’t tolerate violence of any kind at football matches and the disorder which broke out was completely unacceptable."
Disorder broke out on January 28 at the Hawthorns during the FA cup tie.
Members of the public and police officers were assaulted and injured, missiles were thrown onto the pitch and flares were lit delaying the restart of the game.
Police made six arrests on the day for offences including violent disorder and assaulting a police officer.
All have since been bailed whilst the investigation continues.
