Paris St Germain forwards Neymar and Kylian Mbappe are being closely monitored after both suffered injuries on international duty, the Ligue 1 champions have announced.
Neymar was forced off with a groin injury after just eight minutes of Brazil's 1-0 victory over Cameroon in Milton Keynes on Tuesday.
And club team-mate Mbappe sustained a shoulder injury after an awkward landing during France's 1-0 win over Uruguay in Paris.
PSG, who host Liverpool in a crucial Champions League tie next Wednesday, confirmed they would reassess both Neymar and Mbappe in the next 48 hours.
A statement on the club's official website read: "Neymar Jr and Kylian Mbappe have undergone medical examinations today that confirmed: for Neymar an elongation of the right adductors. For Kylian Mbappe a contusion of the right shoulder.
"A period of 48 hours of care will be observed to judge the clinical course."
Neymar believes the injury he sustained is "nothing serious", while - after the game - Brazil boss Tite would not discuss the injury. The player himself said in a message posted on Instagram: "Thanks to everyone who sent me messages wishing a good recovery, I think it was nothing serious."
Brazil team doctor Rodrigo Lasmar also suggested Neymar's issue was not a major one.
Lasmar was quoted by SporTV as saying: "He has been evaluated, has already initiated the treatment. (He) will need a little more time for a better evaluation, an image exam, but at first it is nothing important."
Neymar was replaced at Stadium MK by Everton's Richarlison, who scored the only goal just before half-time.
