West Ham United have suffered an injury blow to new signing Carl Jenkinson.
Jenkinson looks set to miss the start of the season after suffering a hamstring injury on his debut in Germany, says the Daily Mail.
The Arsenal defender only joined the Hammers on a season-long deal on Thursday but was forced off after 60 minutes of the 2-0 defeat to Malaga in Gelsenkirchen.
Jenkinson's injury is the latest blow for boss Sam Allardyce who has already lost striker Andy Carroll until December following ankle surgery and is without right-back Guy Demel who has a hamstring problem.
