Liverpool midfielder Thiago Alcantara has seemingly emerged as a doubt for Wednesday's Premier League affair with Fulham at Anfield.
The Spaniard was absent from Sunday's 4-3 win over Tottenham Hotspur for unexplained reasons, but he was seen limping towards the dugouts, sparking fears of another potential injury.
Calvin Ramsay (knee) and Stefan Bajcetic (adductor) are long-term absentees for the hosts, who are also without Naby Keita and Roberto Firmino - both of whom are nursing muscular problems - while Diogo Jota is a fresh doubt with a knock.
Furthermore, the Liverpool doctors have also been tasked with assessing Jurgen Klopp's hamstring/adductor concern, which he sustained during the manic celebrations after Jota's last-gasp winner.
The injured Reds boss should stick with a largely recognisable backline, but Andrew Robertson did not cover himself in glory on Sunday and could make way for the fresh legs of Kostas Tsimikas.
Trent Alexander-Arnold, Alisson Becker, Ibrahima Konate and Virgil van Dijk should be in no danger of losing their spots, and the same can be said for Curtis Jones and Fabinho in midfield.
Harvey Elliott was given the nod at the weekend, but Klopp should now consider recalling the more experienced head of Jordan Henderson, especially if Thiago's concern rules him out again.
Luis Diaz marked his first start since October with an early goal on Sunday, but Klopp may deem it too risky to field the Colombian from the first whistle twice in the space of a few days. As a result, Darwin Nunez could return to the forward line alongside Mohamed Salah and Cody Gakpo.
Liverpool possible starting lineup: Alisson; Alexander-Arnold, Konate, Van Dijk, Tsimikas; Henderson, Fabinho, Jones; Salah, Gakpo, Nunez
