Benoit out?

Saw a few minutes ago where it appears that Joaquin Benoit had surgery which will knock him out for all of the 2009 season. Shame if true, as he’s developed a nice career as a reliever, now that he’s finally figured out what works.
He’s the elder statesman on the Rangers roster, nobody’s been here on the active roster longer than he has.
I bet you it means we might get some movement regading the bullpen and the “Hot Stove”. Who would you bring in to replace him, or just use another kid from the farm?
