Brown may be on borrowed time but a win or even a draw against Owen Coyle's Clarets would earn him a stay of execution.
A club source confirmed to The Sun: "The owner and the new chairman will be at Turf Moor for the game.
"The new chairman wants to see how the team are performing and if they're responding to their manager in the way they should be."
That is no sweat for Brown, who says he has the "one million per cent" support of his players.
He insisted: "I have been on trial every day of my life, so nothing changes. But it has not been difficult to deal with at all. If anything, it sharpens your focus.
"Sure, this is a big game but the reason why it is a big game is because it's the next three points which are at stake.
"I am confident we will be a Premier League club next season."
