Query posts in archive.php

I am trying to run an extra query within the archive.php. But everytime time it executes, it returns the same results which are not the results that I am after.

Below is a copy of my code that I am running in the archive file, which is located before the if (have_posts()) : while (have_posts()) : the_post(); code.

The code should get the slug of the tag that I am viewing, and use that to check if there is another post in a different post type with the same slug.

$tag       = get_queried_object();
$tag_title = $tag->name; // Same as single_tag_title()
$tag_slug  = $tag->slug;
$tag_id    = $tag->term_id;
$CheckForPost = array(
	'post_type' => 'player-profiles',
	'post_status' => 'publish',
	'posts_per_page' => 1,
	'post_slug' => '$tag_slug'
);
$GetProfileCheck = null;
$GetProfileCheck = new WP_Query($CheckForPost);
if (have_posts()){
	// return true
}else{
	// return false
}
