Kieran Trippier is a doubt for England duty after being forced off in Tottenham's win at Crystal Palace with a groin problem.
The right-back was withdrawn after just 24 minutes at Selhurst Park on Saturday and must be assessed by both Spurs and England medical staff ahead of the games against USA and Croatia.
After his side triumphed 1-0 thanks to a first goal for Juan Foyth, boss Mauricio Pochettino said: "I hope that it's not a big issue (for Trippier). We don't know.
"The medical staff is going to assess, and the medical staff with England will assess as well. It was his groin."
Trippier was one of five Tottenham players named in Gareth Southgate's squad for the upcoming friendly against the USA and UEFA Nations League clash with Croatia.
He was also one of three Spurs players that picked up knocks in the build-up to and match against Palace, with Davinson Sanchez missing out and Erik Lamela needing stitches to a gashed head.
Lamela, goalscorer Foyth and third-choice Spurs keeper Paulo Gazzaniga were all named in the Argentina squad last week to face Mexico twice on November 17 and November 21.
