The 22-year-old was hurt during the epic 4-3 Europa League quarter-final victory over Borussia Dortmund at Anfield on Thursday.
Can went off 10 minutes before the end, soon after Mamadou Sakho had levelled the score at 3-3 and before Dejan Lovren headed Liverpool’s stoppage-time winner.
The German will hope to recover in time for the European Championship in France in June.
