West Ham new-boy Julien Faubert could be a doubt for the start of the new season after suffering an ankle injury.
The 23-year-old France midfield man was carried off in the 1-0 friendly defeat in Austria against Czechs Sigma Olomuc.
Faubert, a £6.1m signing from Bordeaux, left the ground with his leg in a brace and will undergo test to determine the extent of his problem on Wednesday.
West Ham fear Faubert could face a lengthy injury lay-off in a major blow for boss Alan Curbishley.
