England boss Gareth Southgate admitted on Thursday he had named a number of injury doubts in his squad as he could not yet be certain who would be unavailable for both matches. Maddison's ankle issue seemed to have been played down when Southgate revealed Newcastle United striker Callum Wilson was most at risk of pulling out.
"Some of those, we could lose one today after a scan, we could lose one tomorrow. We don't really know. You'd be amazed at how complicated it is picking a squad because all clubs are of course sensitive to information and you're trying to piece everything together," Southgate said.
"So I couldn't be certain that everybody that is in that squad will be there on Sunday night [when the squad reports for duty], varying levels of doubt. With that, Callum is probably the biggest level of doubt, Callum Wilson, but equally I'm pretty confident that the others can get through and they're all keen to be in the squad so that's a really good sign."
Arsenal winger Bukayo Saka is also a doubt to reconvene with the England camp after sustaining a heavy blow and being substituted late on in the Gunners' 2-0 win against Sevilla in the Champions League.
