Diakhaby was pictured crying in the tunnel and had to be replaced as his Valencia side re-emerged to resume the game.
A whole host of statements between both the clubs and individuals involved have since been released, with Cadiz protesting their player's innocence and both Diakhaby and Valencia standing by their initial allegations.
Following an investigation into the matter, La Liga have now revealed they have not been able to prove the allegations are true, though they will continue to analyse the footage available.
“After an analysis of all the elements, it was concluded that in none of the available media was found any proof that the player Juan Torres Ruiz [Juan Cala] insulted Mouctar Diakhaby using the alleged terms," the statement read as reported by The Athletic.
