Juventus defender Armand Traore is set to miss about a month.
The Frenchman, on loan from Arsenal, injured his left thigh during training on Saturday and will now be sidelined for about four weeks.
After having further tests, Traore was diagnosed with a muscle strain and will now have to wait even longer to make his debut with Juventus.
The 20-year old found it hard to break into the Arsenal first team, prompting Gunners boss Arsene Wenger to send him out on loan but it seems Traore's bad luck has followed him to Italy.
