From Rotoworld:

Justin Duchscherer (elbow) is expected to begin playing catch on Tuesday.
He estimates that he's about a month away from throwing off a mound in a game, and considering that he's likely to go on a minor league rehab assignment prior to being activated, it looks like he could remain sidelined until early June.

yahoo's player note on him also says he's eyeing an early june return.
