South Korean Siu Kim withdrew from the Travelers Championship in the second round on Friday due to a back injury.
Kim, who shot 71 overs in the first round, joined Jordan Spieth and Brian Campbell to depart the tournament early in Cromwell, Connecticut.
Kim was eight years old in the tournament when he retreated Friday after posting three bogeys and two double bogeys on 12 holes.
Spieth headed to Clubhouse 12 Hall in his opening round on Thursday due to a neck/back injury. Campbell retreated before the first round began with a shoulder injury.
Kim, 29, has five career victories on the PGA Tour and is ranked 61st in the four world golf rankings. He was tied to eighth place in the PGA Championship at Quail Hollow last month.
Travelers are the final of eight signature events in 2025, featuring a $20 million wallet.
