Mad Men star Jon Hamm says he is "fine" despite an upcoming procedure to remove a polyp on his vocal cord.
In an interview, a raspy-sounding Hamm said the "simple injury" was from overuse of his voice. "Because I talk a lot," he added.
Besides the polyp, the 42-year-old actor insisted that he was "healthy as a horse".
Hamm's publicist Erica Gray said he would be having a routine outpatient procedure.
Next month US viewers will see Hamm star opposite Harry Potter star Daniel Radcliffe in the mini-series A Young Doctor's Notebook, based on a collection of short stories by Russian playwright Mikhail Bulgakov.
Hamm described the series, originally shown in the UK, as "darkly comic", ''gory" and "fun".
