A shock for travelling Hearts fans in the Scott Pittman Testimonial match against Livingston, as their favourites lost 2-1 at Almondvale.
Palmer fired Livingston ahead after 22 minutes, meeting a cross into the six-yard box to head home.
And The Lions doubled their lead when Sinclair headed past Fulton from close range.
Hearts’ new singing, Renaud, reduced the deficit after 41 minutes and the Jambos new management team made changes.
They failed to find the leveller.
