Mariska Hargitay

Law & Order: SVU's Mariska Hargitay has been hospitalized for the third time in as many months. "She is undergoing routine tests and expects to be feeling better soon," a spokesperson for the NBC series told TVGuide.com in a statement.

Hargitay went to the hospital Wednesday morning after experiencing some discomfort relating to a pneumothorax — or collapsed lung — she suffered in January.

While the SVU shooting schedule has been shuffled to accommodate Hargitay's absence, a source on the set indicates that production will not be affected.
