Pulling date from an object

So we have an OU we we put deleted users and in the description we put something like

as per request blah, to be deleted on 05/14/2016 by system

So, I'm struggling with just pulling this part of the description in AD object get-aduser

So here is what I have so far

$users = get-aduser -searchbase "ou=blah,dc=blah,dc=com" -filter '*"

$users | select -first 1 | select name,@{n='description';e={($_.description -match '\d{1,2}\/\d{1,2}\/\d{4}')}} | ft -autosize
