Sam Horsfield has withdrawn from the Great Britain and Ireland Walker Cup team, citing personal reasons.
He will be replaced on the 10-man squad by Ewen Ferguson.
Horsfield, a freshman at Florida, is the second-highest ranked Englishman in the world, at No. 22 in the rankings. He recently reached the quarterfinals of the Western Amateur and the Round of 32 at the U.S. Amateur.
When reached Monday, Horsfield's coach at Florida, J.C. Deacon, said: "Sam had to W/D for some very personal reasons. He's an amazing kid and is making the best of the situation."
The Walker Cup will be held Sept.
