Chelsea's Enzo Fernandez to miss Christmas Eve match against Wolves
Argentine international Fernandez was substituted after just 32 minutes in Chelsea's League Cup quarter-final win over Newcastle United on Tuesday.
"Enzo is going to be out for the game against Wolverhampton," Pochettino said on Friday. "We will see if he can be involved again as soon as possible.
"We already have information that it was a hernia and he also didn't feel well (during the game)."
Pochettino added that Fernandez's injury was not major and that Fernandez's rehabilitation would not pose a problem for the group.
Chelsea, who are 10th in the league standings, will be looking to end a three-match away-game losing streak against the 13th-placed Wolves.
