Liverpool striker Diogo Jota has suffered a thigh injury on Portugal duty.
Jota, 25, was a second half substitute for Portugal in their 1-0 defeat to Switzerland in their Nations League group stage fixture on Sunday.
The Portuguese Football Federation (via the Liverpool Echo) have informed Liverpool of the injury.
The severity of Jota's injury remains unclear as he undergoes assessments with the Portugal national team doctors.
Jota had started both of Portugal's Nations League matches prior to the Switzerland clash.
