PRAGUE, Czech Republic -- Tomas Berdych has a shoulder injury and will miss the defending champion Czech Republic's Davis Cup quarterfinal against Kazakhstan next month.
The sixth-ranked Berdych says on the Czech team's Facebook page that he felt pain Friday morning, a day after he lost 6-3, 6-3 to Richard Gasquet in the quarterfinals of the Sony Open in Key Biscayne.
He said "it was clear to me that I won't be able to play at Kazakhstan."
Another key player for the Czechs, Radek Stepanek, has recovered from neck surgery but is expected to play only doubles.
The Czechs have three players available for the singles -- Jan Hajek, Ivo Minar and Lukas Rosol -- in the April 5-7 matchup on an indoor clay court in Astana.
