Inter defender Alessandro Bastoni was carried off in tears during the Coppa Italia quarter-final against Roma with what appeared to be a badly-sprained ankle.
The centre-back fell very awkwardly during a leap with Nicolò Zaniolo just before half-time at San Siro this evening.
The replays suggest his right ankle turned completely the wrong way as he landed and he was visibly in pain, as teammates immediately called for a substitution.
He was carried off by two members of the medical staff and tests will be required to check the extent of the damage.
This really was not a good day for Bastoni, who had also received a two-match Serie A ban for insulting the officials and arguing with Milan left-back Theo Hernandez during the derby.
There are genuine concerns that the sprain could potentially keep him out for the Champions League Round of 16 against Liverpool next week, or even Italy’s World Cup play-offs in March.
