He gets a September call-up and position with the Rockies "at the end of his playing career."
As long as he doesn't start more than one game a week in September, it'll work.
Update [2006-8-14 17:5:45 by Rox Girl]:
In related bring-em-back to the fold news, the Rox are apparently talking trade with the Astros for Preston Wilson. So long as a P-dub return doesn't cost any real prospect (and it likely won't with the way he's been playing and especially since he was DFA'ed) it could be another flyer worth looking at.
