Ahead of Hoffenheim's Champions League qualifier clash against Liverpool next week, the German outfit have been left concerned over the fitness of one of their main strikers, Sandro Wagner.
Wagner's 11 league goals last campaign helped fire Hoffeneheim to a fourth place finish in the Bundesliga, seeing them enter the qualification rounds for the Champions League. If the injury sustained by the German international is serious it will be a big blow for Julian Nagelsmann's men.
The 29-year-old striker was withdrawn from Die Kraichgauer's pre-season friendly against Bologna after just eight minutes on Sunday, as reported by Liverpool Echo.
It looks certain as though Wagner will miss Hoffenheim's clash against Rot-Weiss Efurt in the DFB Pokal on August 12 as well as running the risk of missing Liverpool's visit to Wirsol Rhein-Neckar-Arena just three days later.
Jurgen Klopp's men kick off their season on Saturday as they face Watford in the Premier League at Vicarage Road, a fixture they won 1-0 in the 2016/17 campaign, courtesy of an Emre Can wonder goal.
After what has been a turbulent transfer window for the Merseyside outfit, with new recruits coming in the form of Mohamed Salah, Andrew Roberson and Dominic Solanke, Liverpool will now be looking to get the new campaign off to a winning start and ensure their passage to the Champions League group stages.
