The Honduran was sent off just 12 minutes into the St James' Park contest for a challenge on Magpies striker Papiss Cisse.
The decision also resulted in a penalty from which Demba Ba fired the hosts into a lead which they would not surrender.
Latics boss Roberto Martinez said: "We will look into it. The red card obviously has to be because he is stopping a clear goalscoring opportunity.
"It's difficult to see how a striker is going to score a goal if the ball is divided between two players.
"Both players are allowed to challenge for the ball. As a defender, you are always going to be strong; as a striker, you are going to invite the contact.
"It is shoulder to shoulder for me. What is important is that the contact was shoulder to shoulder, and that's allowed.
"In the laws of the game, you are allowed to challenge for the position. We will have to look into it if we can appeal for the red card."
