Germany appear likely to be without Mats Hummels when they face Scotland this coming weekend in a Euro 2016 qualifier.
He missed the contest with Argentina on Wednesday night, with Germany put to the sword in an Angel di Maria inspired 4-2 victory.
Manager Jogi Low confirmed to Sport1 after the loss that he did not expect Hummels to be fit for the weekend.
His absence will certainly be making Borussia Dortmund fans a little nervous, given their new captain's importance to the side.
Dortmund have a key Champions League fixture on September 16, at home to Arsenal, a game which can shape the direction of the group and may just influence top spot, with due respect to Galatasaray and Anderlecht.
Hummels missed the corresponding game at the Westfalenstadion last season, and his absence was sorely felt by the home side.
As Aaron Ramsey ghosted into fire a close range winner in a memorable victory for the Gunners, it was easy to wonder if Hummels would have snuffed out the opportunity before it even arose, had he been in action.
Dortmund have already seen midfielder Nuri Sahin ruled out of the game with a knee injury, undergoing surgery earlier this week.
Arsenal have injury worries of their own for the tie, with Mesut Ozil classed similarly to Hummels by Jogi Low, listed as a doubt for the weekend.
If Arsenal can get their playmaker fit and ready to play, and Dortmund cannot get their key defender healthy on time, the Gunners will have a distinct advantage, and this will be an interesting scenario to keep an eye on over the next fortnight.
