The Reds captain came off in the first half of the 3-2 friendly defeat to the Dutch.
"Until we know exactly what has happened it is difficult for us to presume anything," said Dalglish. "I have fantastic respect for 'Pearcey' - he played for us (under Dalglish at Newcastle)."
He added: "He is a really straight, honest guy so I don't think he would do anything harmful to the football club."
Gerrard had played 120 minutes in the Carling Cup triumph over Cardiff on Sunday and was back at Wembley a little over 72 hours later.
He was named in England's starting line-up but lasted just 32 minutes before coming off complaining of a hamstring problem.
Liverpool have yet to assess the extent of the problem, as the players are not due back at the club's Melwood training ground until Thursday afternoon.
