The power struggle at Concacaf took another bizarre turn after its executive committee voted to suspend its own acting president, Lisle Austin, for an alleged "rule violation".

The Barbados official was appointed to lead the North, Central American and Caribbean governing body last week in the absence of Jack Warner, who was suspended by Fifa pending an inquiry into the bribery allegations which overshadowed Fifa's congress in Zurich.

Austin's first action when he assumed the role on Tuesday was an attempt to sack Chuck Blazer – the whistleblower behind the allegations against Warner – from his role as Concacaf's general secretary. Austin told Blazer he had "grossly insulted" Caribbean associations by claiming they had accepted bungs, and had no place continuing his work with the body.

However, Concacaf's executive committee immediately overruled Austin's action as an "unauthorised move" and released a counterstatement which concluded: "Chuck Blazer continues as general secretary and with the full authority of his office."

Austin responded to that statement on Wednesday by declaring it "illegal" and alleging that Blazer had written it himself and sent it out to the media by "trespassing" in the Concacaf press office. Austin said Blazer was exhibiting "blatant disregard for procedure" and "waging a war" against him.

That appears to have been too much for the Concacaf executive committee, which announced that it had banned Austin. The statement said: "Lisle Austin has been provisionally banned from all football activities within Concacaf and at the national level by a majority of the Concacaf executive committee members for apparent infringement of the Concacaf statutes.

"As the most senior vice-president of Concacaf, Alfredo Hawit now assumes the role of acting president."

Concacaf has asked Fifa to extend Austin's suspension worldwide until his full hearing on 13 July.
