The French side has issued a worrying injury update regarding one of their brightest stars less than a month away of their game against Los Blancos.

There were good and bad news for PSG on today's training session, as Lionel Messi returned to the team's training sessions after dealing with his COVID-19 diagnosis. The bad news for Les Parisiens came as Kylian Mbappé's availability for their upcoming games has been jeopardized due to a groin injury.

In a brief press release, the club revealed that their rising star will not be available for an indefinite period of time as a result of this injury.

"Kylian Mbappé is undergoing treatment for pain in his left groin. A follow-up assessment will be done on Friday to see how it is progressing," the club informed in their daily medical update.

This brief report by Mbappé raises doubts about his availability for the team's crucial clash against Real Madrid in the UEFA Champions League. Mbappé's absence would represent a serious dent to the team's chances of success against Ancelotti's team, where some believe Mbappé will be playing next season.
