Daniel Berger withdrew from this week’s PGA Tour stop at the John Deere Classic on Monday.
Berger, a four-time Tour winner and member of the victorious U.S. Ryder Cup team last year, didn’t specify his injury, but Tweeted that he is “working on getting back to 100% but do not feel prepared to tee it up on Thursday.”
Berger previously withdrew from the Vidanta Mexico Open in May prior to the start of the event and also had to pull out of his title defense in February at the AT&T Pebble Beach Pro-Am. At the time, he said he was dealing with a joint sprain in his lower back. He told PGA Tour.com that he suffered a sacroiliac joint sprain, the part of the body that links the lower spine to the pelvis, earlier this year and played through it at Torrey Pines during the Farmers Insurance Open.
