Marco Rodriguez, who sent off Italy's Claudio Marchisio in the same Group D fixture, now has the task of keeping order in Sao Paulo for Tuesday's game.
Rodriguez did not see the incident involving Suarez and Chiellini during the match, which led to the Uruguay star being thrown out of the tournament and banned from football for four months.
Rodriguez has refereed at three World Cups before but has never officiated in a knockout stage match.
News of his appointment come as Germany midfielder Bastian Schweinsteiger warned on Sunday for the match officials in the semi-final to keep an eye on Brazil's physical approach.
"Hard challenges are definitely are part of their game, it's something we have to be careful of and the referee too," Schweinsteiger said.
