Liverpool signing Jeremy Jacquet faces a spell on the sidelines after suffering a shoulder injury playing for Rennes.
The 20-year-old French defender, who agreed a £60m move to Anfield last week, is set to join at the end of the season.
He fell awkwardly in the second half of Rennes’ 3-1 Ligue 1 defeat at Lens on Saturday, when defender Abdelhamid Ait Boudlal also suffered a muscular injury.
Rennes manager Habib Beye said: “It’s definitely quite serious for both of them.”
