Verbruggen fell heavily after being knocked while catching a ball in the 2-1 win over Uzbekistan, forcing him to hobble off.
"He did not take part in training. We have to wait and see and hope that he can be involved on Sunday," coach Ronald Koeman told a press conference at the team base on Wednesday.
But the coach offered a positive outlook later.
"It's only a bruise, so we don't know yet how things will be on Sunday. We are hopeful, but we'll have to see how far along he actually is."
Koeman said it was not a concern because he had other good goalkeepers.
"Who might play in goal? We still have to decide that. We will provide clarity on that during our discussions with the goalkeepers," the coach added.
Mark Flekken took over from Verbruggen in the match against Uzbekistan, and the other choice is Robin Roefs, who won his first cap a week ago when the Dutch lost a friendly to Algeria in Rotterdam.
Koeman was also asked if he had made up his mind who would lead the attack in Dallas on Sunday, a question referring to Memphis Depay’s fitness after a thigh injury that has limited his playing time over the last three months.
The Netherlands' record goalscorer has struggled in 2026, playing just four league games for Corinthians and averaging a Flashscore Rating of 6.5
"It’s Wednesday and we play on Sunday, but I think if I still have doubts then I haven’t done my homework properly.
"We know that Memphis has had some injuries and hasn't played in recent weeks, but now he's back. Every day he is getting closer to his top level.
"He is our all-time leading goal scorer and we need him, just like we need all the other players," Koeman added.
The 2026 World Cup will be held from June 11th to July 19th in the United States, Canada and Mexico. The tournament will feature 48 national teams and will be played in 16 modern stadiums.
