Juventus saw Giorgio Chiellini limp off against FC Porto with yet another calf problem, adding to the injury crisis.
The veteran was starting because Leonardo Bonucci is out of action with a muscular issue, along with Juan Cuadrado, Arthur Melo and Paulo Dybala.
It looks as if the Bianconeri will have even more injury problems to deal with going forward, as Chiellini lasted just 35 minutes at the Estadio do Dragao.
According to initial reports, it was yet again a calf injury, an issue that has been plaguing the defender for several years now.
It appeared to be his right calf that was causing the problems.
Chiellini was replaced by Merih Demiral.
