Muskat: Source says Haren/Marmol swap "not happening"

Carrie Muskat just tweeted that a Cubs source has told her that a trade of Dan Haren for Carlos Marmol is "not happening."

Ken Rosenthal had tweeted earlier that the trade was dependent upon Marmol waiving his no-trade clause.

It isn't clear whether the Cubs source is saying that Marmol invoked his no-trade clause or if the source is simply saying there isn't a deal.
