Juventus said in a statement that Costa had suffered a “second degree injury to the right thigh” and that his condition would be evaluated within 15 days.
The 29-year-old Brazilian international was injured during the match his team lost to host Udinese 1-2 on Thursday.
The match against Lyon is scheduled to take place at “Allianz Stadium” for Juventus, knowing that the French team won back home, with a goal without a return.
Costa, despite his frequent injuries, is an important element in Juventus’ ranks. Coach Maurizio Sarri often depended on him in the second half.
