World No.8 Karolina Pliskova has pulled out of the Czech team for next week's Fed Cup final against defending champions the United States due to a calf muscle injury.
The Czech team says Pliskova was injured last week during the WTA Finals in Singapore, where she wore tape on her right calf and lost to Sloane Stephens of the United States in the semi-finals.
She will be replaced by debutant Barbora Krejcikova, who leads the WTA doubles rankings with her partner Katarina Siniakova.
World No.7 Petra Kvitova will lead the Czech side in Prague next weekend, joined by Barbora Strycova, Siniakova and Krejcikova.
The US line-up is missing their big names.
With Serena and Venus Williams unavailable along with Stephens and Madison Keys, captain Kathy Rinaldi's top-ranked player is world No.35 Danielle Collins.
She will be joined in Prague by 48th-ranked Sofia Kenin, No.63 Alison Riske and Nicole Melichar, the world's 15th-ranked doubles player.
The US have dominated the Czechs in Fed Cup play, posting a 10-2 record.
