Liverpool midfielder Emre Can has suffered an injury scare while on duty with Germany at the Confederations Cup

Can is a doubt for the world champions' closing Group B match against Cameroon after withdrawing from Saturday's training session in Sochi.

Germany boss Joachim Low did not specify the precise nature of the injury, but described it as a "minor" problem sustained when the 23-year-old's "boot got stuck in the grass".

"During training, Emre Can has sustained a minor injury," Low told a pre-match new conference at Fisht Stadium.

"He bent over on the pitch. His boot got stuck in the grass. We will have to see how he feels because he had to break off training."

Low boasts a plethora of midfield options in an experimental squad and his side sit level on points with group leaders Chile following the sides' 1-1 draw in Kazan on Thursday.
