Jerome Boateng hobbled out of Bayern Munich's Champions League semi-final against Real Madrid with an apparent hamstring injury on Wednesday.
Boateng pulled up shortly after Joshua Kimmich fired Bayern into a 1-0 lead in the first-leg clash at the Allianz Arena.
The injury makes Boateng a major doubt for the return encounter at the Santiago Bernabeu and could also become a concern for Germany boss Joachim Low ahead of the World Cup in Russia.
Bayern loss Arjen Robben due to a problem with his right leg earlier in the contest and were pegged back by Marcelo's excellent equaliser before half-time.
Hope it's not too serious, Boa! 1-0 April 25, 2018
Low, whose side are among the favourites to win the World Cup, was in attendance in Munich.
