Gonzalo Montiel, the right-back, may have suffered an injury, which could be detrimental to Nottingham Forest.

During the first half of Argentina’s 2-0 victory over Peru on Tuesday, the 26-year-old had to be replaced.

Just before Lionel Messi put La Albiceleste ahead in Lima, Montiel seemed to notice the issue. He then gestured to the bench to be replaced by Lucas Martinez Quarta.

According to the Argentine publication El Intra, Montiel has a muscular problem and will be returning to Nottingham this week for examinations.

With multiple injury concerns for Forest already, manager Steve Cooper will be hoping to have Montiel healthy for Saturday’s visit by Luton Town to the City Ground.

Many of the issues are in defence, particularly as Montiel might be forced to substitute for fellow right-backs Sergege Aurier and Ola Aina.

Before the international break, during the trip to Crystal Palace, Aurier was substituted at halftime by Montiel because the Ivorian was having trouble with a groin issue.

Moussa Niakhate, who was sent off late in their previous match at Selhurst Park, will miss Luton’s visit, and Felipe is still sidelined due to injury.

However, Nuno Tavares might be getting closer to making a comeback, and Neo Williams ought to be fully healthy again after participating in both of Wales’ games during the intermission.

When Tavares sustained an injury last month while playing Manchester City at the Etihad, Montiel was the player who took Tavares’ position.

The Argentine made his first competitive appearance for his country since earning the World Cup final penalty, and his only two starts for Forest were against Burnley at home in the league and cup.

Even though Montiel had to go back from South America, he would have been expected to start against Luton; but, considering the extent of the injury and the lack of a timeline, that seems doubtful.
