The Tennessee Athletic Commission is considering disciplinary action – including fines and suspensions – for five individuals following a post-event brawl at the April 17 "Strikeforce: Nashville" event at Bridgestone Arena.

Christopher Garrett, director of communications for the state of Tennessee, today confirmed with MMAjunkie.com that the TAC determined five individuals engaged in "conduct that is detrimental to a professional contest of unarmed combat."

The state will not release the identities of the individuals until administrative actions are finalized.

The CBS-televised brawl occurred after Strikeforce middleweight champion Jake Shields defended his title with a win over Dan Henderson in the night's main event. Preliminary-card fighter Jason Miller interrupted Shields' post-fight speech to demand a rematch of their November meeting.

The televised confrontation led to shoving, which eventually led to an all-out brawl. In addition to Shields and Miller, the scrum included three of Shields' training partners: Strikeforce fighters Gilbert Melendez and Nick Diaz, as well as UFC fighter Nate Diaz.

A video that CBS posted on its website after the event shows as many as 25 individuals in the cage during the time of the brawl. However, it's difficult to determine who's engaged in the scrum and who is simply trying to break it up.

Tennessee officials, who today held a commission meeting to discuss the matter, can not confirm if those five fighters are the same five individuals also being considered for disciplinary action.

In three of the cases, the commission found probable cause to authorize a formal hearing for a civil penalty of $20,000 each and associated costs, as well as a nine-month suspension. Each individual can agree to a "consent order" that would allow him to skip the hearing and agree to a $5,000 fine and three-month suspension.

In the fourth case, all of the particulars are the same except that the settlement fine would be $7,500. The larger amount represents an additional civil penalty because the individual did not respond to the commission's inquiry as instructed.

A fifth case also recommends the larger $7,500 settlement fine because the individual did not respond to the commission's inquiry. The individual is not licensed with the state, and the complaint also alleges "unlicensed activity," according to Garrett.

A search of Tennessee's official license database shows that Shields, Miller, Melendez and Nick Diaz have active "combatant" licenses with the state; Nate Diaz does not.

State officials did not immediately confirm when the hearings would take place in the event one or more of the individuals requests one
