Confusion reigned at Roots Hall after chairman Ron Martin's announcement last Sunday that boss Sturrock had been sacked but, bizarrely, would return to take charge for the Wembley showdown against Crewe on April 7.
The Scot himself then confirmed that he will not only be leading the team out but would also be taking training all next week and picking the team.
That threatened to provide a unprecedented situation after former Hull and Preston boss Brown was confirmed as United's new manager on Monday, starting his reign with an Easter double-header in League Two over the coming days.
Yet exactly who would be pulling the strings next weekend still remained unclear after Brown was unveiled to the press on Tuesday morning, with the former Hull boss stating the situation "will be resolved in the next few days".
And Southend's official twitter feed has on Thursday afternoon posted: "Paul Sturrock has announced he has politely declined the chairman's offer for him to manage the team at Wembley.
"Paul will travel with the supporters to the game and sit in amongst the fans. He says he is looking forward to a few beers with you all."
Brown will now manage Southend in the showpiece final against Crewe as the Essex club play in their first-ever Wembley final, where they will be backed by around 30,000 supporters.
