The injured Lidewij Welten has been included in the Olympic selection of the Dutch hockey players.
The attacker is still uncertain due to a thigh injury.
Welten suffered a serious thigh injury in the championship match of her club Den Bosch in May, as a result of which she had to miss the European Championship in her own country.
In Amstelveen, the Orange won the European title last Sunday at the expense of Germany.
National coach Alyson Annan already announced that Welten would most likely be selected for the Olympic Games.
If she is unexpectedly not fit enough just before the Games, a reserve player will be flown in.
Welten previously announced that a race against time awaits her to be fit in time in Tokyo.
Thirty-year-old Welten is one of the most successful hockey players of all time.
The 217-time Orange International won two Olympic titles, two world titles and three European titles.
She has already participated in the Olympic Games three times, in 2008, 2012 and 2016. The Olympic Games in Tokyo start for the Netherlands on 24 July.
National coach Annan has also made a place for Xan de Waard in the sixteen-man selection.
The playmaker was still missing at the last European Championship due to an injury, but according to Annan she is fit enough to participate in the Games.
Annan also chose Josine Koning as first goalkeeper and also selected 21-year-old Felice Albers, who only played ten international matches in Orange.
Sanne Koolen, Freeke Moes and goalkeeper Anne Veenendaal have been designated as reserve players.
