Liverpool are confident the muscle tear suffered by Joel Matip against Borussia Dortmund is not a long-term problem but he will play no further part in the International Champions Cup.
Matip was withdrawn midway through the first half of Sunday's 3-1 defeat in Charlotte, with Jurgen Klopp allaying fears the thigh problem was related to the injury that kept the defender out of the Champions League final.
"It's not the same injury, it's another muscle, but it's a muscle, obviously. It looks like, hopefully, only a little tear," the Liverpool manager said.
Klopp had hoped for a positive update on the 26-year-old but Liverpool confirmed on Monday that the tear would see Matip return to Merseyside.
