wonderm00n on "[Plugin: WordPress SEO by Yoast] Disbale on Specific Pages"

I got it working for wpseo_canonical but not for wpseo_description.

Here's the code. Any idea?

//Remover YOAST na página de empresas
	add_filter( 'wpseo_canonical', 'wpseo_canonical_exclude' );
	function wpseo_canonical_exclude( $canonical ) {
		global $post;
		if ( $post->ID == 5751) {
    		$canonical = false;
    	}
		return $canonical;
	}
	add_filter( 'wpseo_description', 'wpseo_description_exclude' );
	function wpseo_description_exclude( $description ) {
		global $post;
		echo $description;
		if ( $post->ID == 5751) {
    		$description = false;
    	}
		return $description;
	}
