Defer stats.wordpress.com.js

Hi, in http://developers.google.com/speed/pagespeed/insights/ i have this:

remove render-blocking javascripts, and the only file to defer is: http://stats.wordpress.com/e-201420.js

How can i put defer attribute to jetpack/modules/stats.php:<script src=”$http://stats.wordpress.com/e-$week.js” type=”text/javascript”></script>

with defer=”defer” is fixed?

<script src=”$http://stats.wordpress.com/e-$week.js” type=”text/javascript” defer=”defer”>

Thanks for you support.
