A precaution for qualified Germany perhaps, but one worth bearing in mind for Arsenal heading into the weekend.
The news Per Mertesacker is on the bench for Germany's meaningless qualifier should be good news for Arsenal fans, wary of him picking up an injury.
But the reason he is not in Germany's starting line-up for the away game against a Zlatan-less Sweden is he was not 100 per cent heading into the game.
German news reports claim the centre-back is suffering a cold, and has been rested up with that in mind.
Kicker reported on Tuesday that Mertesacker was suffering, and would be assessed in training on Wednesday morning.
Coach Jogi Low was evidently not happy with the defender's recovery, and as Bild report this evening, Mertesacker is absent due to a cold.
The temperature in Stockholm, where the game is being played is just seven degrees Celsius, which can't be helping the defender out.
Arsenal play on Saturday at home to Norwich, and management will hope they can call upon the reliable German. If we were betting, we'd tip him to be fit, but at this stage it's worth fans knowing about just in case.
Laurent Koscielny has himself been recuperating from a minor calf strain which caused him to miss France's friendly with Australia, while Thomas Vermaelen is back in action for Belgium this evening.
How crucial to Arsenal is getting Mertesacker back 100 per cent?
