France captain Guy Forget believes the United States will be significantly weakened by the loss of Mardy Fish in their Davis Cup quarterfinal on Friday.
Both teams were rocked by withdrawals to key players this week.
The ninth-ranked Fish pulled out because of fatigue and was replaced by Ryan Harrison, while Forget is without the 14th-ranked Gael Monfils, a former French Open semifinalist, because of an abdominal injury.
Forget says ''I think these last-minute withdrawals are more harmful for them than for us,'' adding that ''Harrison is a player for the future.''
Courier, who won French Open titles in 1991-92, was tightlipped about why he chose the 19-year-old Harrison, who has never played a live Davis Cup tie.
