AUSTIN, Texas -

Gov. Rick Perry is set to undergo surgery to repair his right clavicle, which has yet to properly heal following a 2009 bicycle accident.

The Texas Governor's Office says Perry will undergo a 90-minute outpatient procedure Friday in Austin.

Performed by Dr. Bruce Malone, the operation requires a single incision roughly three inches long to place a countered plate.

Lt. Gov. David Dewhurst will assume gubernatorial duties if Perry is temporarily unable to serve.

In July, the 61-year-old Perry had stem cells taken from his body that were then grown in a lab and injected into his back during an operation to fuse part of his spine.

Perry later suggested amid his failed presidential run that a sore back had hindered him during the early part of the campaign.
