KANSAS CITY -- Royals right-hander Nate Karns underwent successful surgery for thoracic outlet syndrome on Wednesday in Dallas, manager Ned Yost said Thursday.
Karns likely will be recovered in time for Spring Training.
"Everything went well," Yost said. "Everything went just as expected. They took out the rib, what they normally do."
The surgery was performed by Dr. Gregory Pearl. Karns is recovering at Baylor Hospital.
Yost said Royals trainer Nick Kenney was told the surgery was less invasive than other types of thoracic outlet syndrome procedures. Thoracic outlet syndrome is a condition in which blood flow is restricted because of compressed blood vessels or nerves near the first rib and collarbone.
