Mad Men actor Jon Hamm will have minor surgery on his throat to have a polyp removed.

The star, who plays Don Draper in the acclaimed drama, is scheduled to undergo what is considered to be a routine outpatient procedure.

According to E! he is said to have been overhead talking about the surgery with Mad Men co-star January Jones (who plays Draper's ex-wife, Betty) at an Emmys afters party on Sunday night.

After going home empty-handed from the Emmys, Hamm and Parks and Recreation actress Amy Poehler hosted a 'losers' party' for their industry pals.

"We figured that the winners get celebrated enough, so we thought it was about time that the losers get celebrated," Hamm said.

Mad Men season six is currently running on Tuesday nights on RTÉ Two.
