Brown's fate will now be decided on April 26, the SFA has confirmed.

Brown was accused of breaching a rule which states players, coaches and officials should "act in the best interests of association football". Rule 77 also references "improper" behaviour and using "threatening, abusive, indecent or insulting words or behaviour" and carries a minimum two-match suspension for players.

Players and staff, as well as stewards, were involved in a melee after Rangers left-back Andy Halliday
remonstrated with Brown over his celebrations following his team's 2-1 win at Celtic Park on March 31.

The 33-year-old raised both arms aloft in the direction of the away supporters. Mobile phone footage also showed the midfielder making a gesture with his arm while looking behind him after moving along the main stand touchline past Celtic supporters.

Both clubs face a hearing over the ensuing confrontation on the original May 2 date.
