The Belgian has been sidelined ever since the Blues' Champions League semi-final second leg against Paris Saint-Germain, with reports from earlier last week suggested De Bruyne was struggling with a thigh injury.
With the Champions League final now less than two weeks away, it was important to not risk the key midfielder's fitness ahead of that game.
So far, Kevin de Bruyne has missed Premier League games against Chelsea and Newcastle.

It's unknown whether De Bruyne will play any part in the game against Brighton on Tuesday night, but Guardiola has said, "He's training the last two days and he feels good."
In regards to how important it is to get the Belgium international up to speed, Pep Guardiola also said, "Kevin is important like everyone is important. We will see his level for the next games."
The 29-year-old has recently signed a contract extension with the club that keeps him in Manchester until 2025.
His performances over the last couple of years have seen him be awarded with numerous personal accolades - including last seasons PFA Player of the Year award.
