Doubtful due to intercostal pain, 'Leo' joins an expanded list of 24 players for this meeting.
"Leo Messi trained separately," PSG explained in a statement on Saturday, assuring that "a new point" would be made on Sunday morning.
Among the injured absent on Sunday, the Argentinian midfielder Leandro Paredes (pubalgia) continues his rehabilitation.
German attacking midfielder Julian Draxler "starts his re-athleticization phase on the pitch, with and without the ball", and Argentinian striker Mauro Icardi (quadriceps) "will resume training at the end of next week", added the club.
The young Édouard Michut, suspended after his exclusion in Clermont, finds the group.
