Patrick Cantlay has withdrawn from the John Deere Classic due to an injury sustained while training, casting doubt on his participation in the upcoming British Open at Royal Troon. Cantlay, who was the betting favorite and ranked No. 8 in the world, has been replaced by Russell Knox. His withdrawal shifts the spotlight to other top contenders like Jordan Spieth, Sungjae Im, and Sepp Straka. Spieth, a former winner of the event, returns to TPC Deere Run for the first time since 2015. The John Deere Classic, now in its 25th year under its current name, will feature additional attractions like concerts and a Folds of Honor event to honor military members. Cantlay hopes to recover in time for the Scottish Open next week, which precedes the British Open.
