England will name their 23-strong squad for the Women's European Championship at 17:00 BST on Wednesday.
The Lionesses, who are hosting the tournament, are in Group A with Austria - their first opponents on 6 July - Norway and Northern Ireland.
Coach Sarina Wiegman has to decide which five players to cut from the 28-woman provisional squad she named in May.
Defender Steph Houghton is a doubt having not played since January.
Forward Fran Kirby has not played since February because of fatigue but she is still in contention for the tournament.
Jill Scott is also a doubt.
Teams will be able to make changes to their squad because of illness or injury until the first game.
England play Belgium, the Netherlands and Switzerland in friendlies this month.

The biggest decision for Wiegman is whether she takes Houghton. It would be a big risk given Houghton's lack of playing time this season and the fact she has not played under Wiegman, but her leadership and experience could be considered too important.
Midfielder Scott could certainly provide that experience in Houghton's absence. She has also struggled with injury recently though, so can Wiegman afford to take both Scott and Houghton?
It would be a shock if Kirby was not selected despite her recent illness. She is a hugely talented player who is yet to shine under Wiegman but even if she is not fully fit, she is capable of having a big impact.
Forward Chloe Kelly could be a wildcard. She was superb for both club and country before suffering from a knee injury but returned at the end of the season looking sharp and dangerous for Manchester City. Should Wiegman choose to select her, it could come at the cost of Nikita Parris, who has struggled for form at Arsenal.
Elsewhere, Manchester United captain Katie Zelem may miss out in midfield, while Chelsea's Bethany England and United's Alessia Russo might be vying for one spot as support for striker Ellen White. Everton goalkeeper Sandy MacIver has not made an appearance under Wiegman so is expected to miss out.
