apply_filters('get_the_content', $content) + Except

apply_filters('get_the_content', $content) + Except

I'm using the following function to load my content dynamically:
apply_filters('get_the_content', $content)
However, I would like to apply an excerpt to this method but the only way I know how to do it is this way:
$content = apply_filters('the_content',get_the_content( $more_link_text, $stripteaser, $more_file ));
Is there a way to apply an excerpt with my function? Thoughts?
Best,
Jon
