Roger Federer has confirmed that he will play in Switzerland's Davis Cup playoff tie away to Netherlands at the weekend, the Swiss Tennis Federation said on Tuesday.
Federer will join Stanislas Wawrinka, Marco Chiudinelli and debutant Henri Laaksonen as the Swiss try to keep their place in the world group.
Without him, Switzerland were crushed 5-0 and lost their place in the world group.
Last year, Switzerland regained their place by beating Portugal and Australia, with Federer playing in both ties.
This year, Federer lost both rubbers in which he played -- a singles and doubles -- as Switzerland lost 5-0 to United States in the world group first round.
