Federer fit for doubles in Davis Cup final
Lille, France: Roger Federer is fit enough to play the Davis Cup final doubles with Stan Wawrinka against French pair Richard Gasquet and Julien Benneteau on Saturday.
France and Switzerland ended the first day at 1-1 after Wawrinka defeated Jo-Wilfried Tsonga and Federer lost in straight sets to Gael Monfils in the opening singles on Friday. Monfils won 6-1, 6-4, 6-3.
Switzerland's Marco Chiudinelli and Michael Lammer were initially set to play but Swiss captain Severin Luthi changed his lineup at the last minute.
Federer, who is chasing his first Davis Cup title, is hampered by a back injury but said he expects to play better as the weekend progresses.
Federer and Wawrinka won gold at the 2008 Beijing Olympics but lost the last four Davis Cup matches they played together.
