In the other game on the final day of the round of 16, Switzerland meet Sweden in Saint Petersburg, looking to become the first Swiss team in 64 years to qualify for the World Cup quarter-finals. He will be assisted by fellow American Frank Anderson and Canada's Joe Fletcher.
It should be said that England will face Colombia in the last 16 having not won a knockout match at a major finals since beating Ecuador at the 2006 World Cup.
Geiger also was the referee for Colombia's opener in 2014, a 3-0 victory over Greece. For England, the player to watch is Tottenham striker Harry Kane, who scored five goals in England's wins over Tunisia and Panama before sitting out the loss to Belgium.
England play Colombia on Tuesday at 7pm. "Each one of us here is prepared and ready to play and whoever plays will do their best".
Meanwhile, midfielder Ruben Loftus-Cheek says the Three Lions squad has a point to prove in the knockout stages. In their last eight knockout games at World Cup, they have managed to win only two. He said: "It's going to paralyse the country - even people who don't like football get involved, and the team unites us".
"I think he [Sanchez] is a great player, I don't think any player is flawless, we know things, we know how he plays and he has a lot of strengths".
"We're a team that doesn't carry any passengers", Southgate said.
James Rodriguez, who has been dealing with a calf strain throughout the tournament, was subbed out in the 31st minute of Colombia's last match against Senegal. The Daily Telegraph says that head coach Jose Pekerman was "very worried" about Rodriguez's injury and Colombia "will be holding their breath" for news on the 2014 World Cup Golden Boot victor. "Prediction: Colombia 0 England 2". "Prediction: Colombia 1-2 England AET". "England have hardly covered themselves in glory in tournaments over the last two decades yet they were wasting time and energy and getting distracted thinking about possible quarter-finals and semi-finals".
Colombia's Football Federation confirmed on Saturday that "James Rodriguez underwent a scan today which showed that he is suffering from minor edema, but that there has been no muscle tear".
