Bukayo Saka and Curtis Jones have withdrawn from the England squad ahead of the side's crunch Nations League clash with Finland on Sunday.
Saka was forced off injured in this international break's opening tie against Greece at Wembley on Thursday evening, ramping up concerns from national team and Arsenal fans alike.
The 23-year-old appeared to show some discomfort in his right leg and is thought to be undergoing a scan in a bid to clarify the extent of a potential problem.
'He's being assessed,' Carsley said of his player after Thursday's 2-1 defeat on home soil.
