Adam Lallana's World Cup fitness is in fresh doubt after limping off just five minutes into his appearance in Liverpool's clash with Crystal Palace on Saturday.
The 29-year-old, who has only started one Premier League match this term, was replaced by Dejan Lovren 324 seconds after coming on just after the hour mark at Selhurst Park, which Liverpool won 2-1 through Sadio Mané and Mohamed Salah strikes.
He appeared to tweak a muscle in stretching to challenge Eagles captain Luka Milivojevic, who had opened the scoring from the spot.
Lallana has been plagued by a persistent thigh problem this season, although he was included in Gareth Southgate's latest England squad and featured off the bench against Italy on Tuesday.
But another lengthy lay-off could deny him the chance to prove his readiness for Russia 2018.
