Europe's Suzann Pettersen has been forced to withdraw from this week's Solheim Cup with a back injury.
The Swede, who slipped a disc in her back while on a run in Norway last week, will now be replaced by Scotland's Catriona Matthew
Pettersen will remain with Annika Sorenstam's team so she can support the side.
“I have made this extremely difficult decision to help the European team and give my teammates the best possible chance of success,” Pettersen said in a statement.
“There was no guarantee that I would be fit to compete on Friday morning and I did not want to play unless I was able to give 100 percent. I truly love the Solheim Cup and I will stay and support my team this week in whatever way I can.”
Pettersen, 36, is Europe’s team leader who was sure to be a strong storyline this week after being involved in a controversy over a lack of a concession at the 2015 Solheim Cup in Germany, where American Alison Lee scooped up an 18-inch putt thinking the Europeans had conceded it.
She owns an enviable 16-11-6 record in eight Solheim Cups, and the 19 points she has accumulated in the matches trails only Laura Davies (25) and Sorenstam (24) in the European record books.
“It’s unfortunate that Suzann has to withdraw due to her back injury,” said European captain Sorenstam.
“The Solheim Cup has been such an important part of her career. It was a very tough decision, but I am proud of her and she will still be a leader this week.
“Catriona is a proven Solheim Cup performer who will be able to step right in and play with anybody. She’s ready to go.”
Matthew, 47, will be competing in her ninth Solheim Cup. She is 15-10-8 in the matches.
