The great and famous striker of Portugal, Cristiano Ronaldo's goal in the early minutes of the match saved Portugal and it marked a narrow 1-0 win over 41st ranked Morocco in their second game in Group B of the current 21st edition of the FIFA World Cup 2018.
Worldwide players' union FIFPro said Morocco were putting Amrabat in harm's way.
But global soccer officials condemned the claim made against Mark Geiger, 43, a native of Ocean County, N.J., who denied the allegation against him.
The spokesman added: "Mr. Geiger strongly refutes these claims and categorically states that such a request was not made".
"FIFA would like to remind teams of their duty to respect all principles" of sportsmanship. "I can't tell you anymore".
Morocco fell behind in the fourth minute to a diving Cristiano Ronaldo header, which saw him overtake Ferenc Puskas as the record European global goalscorer, but were on top for much of the contest thereafter. Have a good look at the corner when Portugal scored and have a good look at what their number three is doing and write the truth.

"I'm not disappointed with the performance - I'm very proud of my players and this country", he said.
Morocco lost 1-0 against Portugal to become the first side to be eliminated from the tournament.
Morocco coach Herve Renard singled out Geiger in his post-match press conference, although stopped short of criticising him directly.
The Atlas Lions have yet to pick up a point in Russian Federation after succumbing to successive one goal defeats, first against Iran and then against the European champions; with a final game against Spain still to come.
