ST PETERSBURG, Russia, Oct 25 (Reuters) Russia have suffered a huge setback to their Davis Cup hopes after Nikolay Davydenko and Mikhail Youzhny retired with injuries at the St Petersburg Open today.
Top seed Davydenko quit his second-round match against South Africa's Wesley Moodie with an apparent foot injury while leading 6-2 3-3.
Just 30 minutes earlier eighth-seeded Youzhny pulled out of the 1 million dollar tournament after spraining his right ankle in a doubles match. Swede Thomas Johansson received a walkover into the singles quarter-finals as a result.
Russia host Argentina in the Davis Cup final from December 1-3 in Moscow.
Youzhny's injury appears to be more serious.
The world number 23 was taken to a local hospital for x-rays.
''Medical test will show if Youzhny would be able to participate in any future tournaments for the rest of the year,'' ATP officials said in a statement.
