Liverpool midfielder Jordan Henderson will sit out the Boxing Day Premier League clash with Swansea at Anfield.
Henderson injured his right hamstring early in the 3-3 draw with Arsenal and has been ruled out by manager Jurgen Klopp.
Klopp insisted that while a few knocks were sustained against the Gunners, no others players were expected to miss out against the Swans.
Kyle Naughton has joined the Swansea casualty list.
Naughton suffered a groin injury in Saturday's 1-1 draw against Crystal Palace and Angel Rangel is set to deputise at Anfield.
Swansea are already without Wilfried Bony (hamstring), Ki Sung-yueng (calf) and Kyle Bartley (knee ligaments), while Leroy Fer (back) will be assessed on Christmas Day.
