Contrary to what was initially thought, Davide Calabria was not replaced with Sergino Dest for the yellow card he picked up in the first half. In fact, the reason is due to muscular problems and that is why Stefano Pioli decided to take him off the field before the start of the second half.
The latest report and update is shared by Milannews.it's journalist Antonio Vitiello who said the following:
"(Davide) Calabria was replaced due to flexor muscle fatigue."
