Youzhny replaces Davydenko in Russian Davis Cup line-up

MOSCOW, Sept 23 (Reuters) Mikhail Youzhny has replaced world number four Nikolai Davydenko in Russia's line-up for the first reverse singles of their Davis Cup semi-final against Germany today.

The Germans, who lead the holders 2-1 after winning Saturday's doubles and need one more victory to clinch the three-day tie, also made a switch, replacing their number one Tommy Haas with 206-ranked Philipp Petzschner.

German captain Patrik Kuhnen said Haas could not play after feeling unwell yesterday evening.

World number 11 Haas was trounced by claycourt specialist Igor Andreev in straight sets in Friday's opener while Davydenko, who was suffering from a wrist injury, also lost his singles match, going down to 32nd-ranked Philipp Kohlschreiber in five sets.

Andreev is due to face Kohlschreiber in the final rubber.
