Latest Facebook Comments

On my site, I have a widget which displays Headline – Popular – Comments
in tabs, Headline and Popular work very well, however because I am using the Facebook comments the comments section doesn;t work.

You can see an example here, on the right below the ad: http://worldinsport.com

Here is the code for the Comments tab, how can I change this to show the facebook comments please?

<?php
				global $wpdb;
				$sql = "SELECT DISTINCT ID, post_title, post_password, comment_ID, comment_post_ID, comment_author, comment_author_email, comment_date_gmt, comment_approved, comment_type,comment_author_url,
				SUBSTRING(comment_content,1,45) AS com_excerpt
				FROM $wpdb->comments
				LEFT OUTER JOIN $wpdb->posts ON ($wpdb->comments.comment_post_ID =
				$wpdb->posts.ID)
				WHERE comment_approved = '1' AND comment_type = '' AND
				post_password = ''
				ORDER BY comment_date_gmt DESC
				LIMIT $com_num";
				$comments = $wpdb->get_results($sql);
				foreach ($comments as $comment) {

				?>

				<ul class="latest-comments">

<li>
					<?php echo get_avatar( $comment, '40' ); ?>
					<strong><?php echo strip_tags($comment->comment_author); ?> says:</strong>
					<?php echo strip_tags($comment->com_excerpt); ?>...
					<a>ID); ?>#comment-<?php echo $comment->comment_ID; ?>" title="<?php echo strip_tags($comment->comment_author); ?> on <?php echo $comment->post_title; ?>"><?php echo strip_tags($comment->post_title); ?></a>

</li>
				<?php } ?>
