BA team coach Yogendra Dutt and manager Arvin Singh have been suspended from their positions.
This follows Ba's first loss in the Fiji Sun/Skipper Tuna National Football League to Suva on Sunday.
Singh confirmed receiving the letter from the Ba Football Association on Monday.
He declined to elaborate further on the issue saying that he would comment after meeting the board members.
Dutt, a highly qualified coach, was the recipient of the Fiji Football Association coach of the year award back to back in 2006 and 2007.
Ba's season hasn't been fruitful after beating Nadi to win their 14th Champion versus Champion title in January.
Ba bowed out of Oceania Football Confederation Champions League at the semi-final stage in April.
The Men in Black lost to Amicale FC 2-1 in the first leg and drew nil-all in the second leg.
Ba lost to Nadi 2-0 in the semi-final and then went down 3-0 to Labasa in the 3rd/4th place play-off of the Vodafone Fiji FACT last month.
The side went down to Suva 1-0 in the national league on Sunday.
Ba Football secretary Iliaz Khan refuted certain claims that the duo had been terminated.
Khan did not reveal the grounds of suspension saying it was an internal matter.
He said Dutt and Singh would have to appear before the Ba Football board.
"The board members have work commitments so a date for hearing will be set at their convenience," Khan said.
"It will be done at the earliest."
Khan did not wish to comment on the team's preparations for the National League match against Nadi at Prince Charles Park this evening.
The match will kick off at 7.30pm.
In other matches this weekend, Lautoka will host Rewa at 3pm and at the same time at the ANZ Stadium Suva will take on Navua.
Meanwhile Ba has filed a protest against Suva after the loss.
