The International Hockey Federation (FIH) on Tuesday reduced the three-match ban on Indian forward Shivendra Singh.
Singh will now miss two matches of the World Cup.
He was handed a ban for "deliberately" hitting a Pakistani player during his team's World Cup opener in New Delhi on Sunday.
The verdict of the FIH jury means that Shivendra, who scored a goal against Pakistan on Sunday, will miss Tuesday's crucial game against Australia and the one against Spain scheduled for Thursday.
"We have just been told about the FIH's decision that his ban has been reduced to two matches," Hockey India Secretary General Narinder Batra said.
"We are not at all happy with the decision because the foul was not intentional. We are disappointed with the jury's verdict but we don't have any option now and he will have to sit out," he added.
Tournament Director Ken Read had stated that Shivendra "deliberately" hit Fareed Ahmed by lifting his stick in the 39th minute of the match which the hosts won 4-1, leaving the Pakistani player with a small cut above the eye.
