Messi was named on Friday in coach Edgardo Bauza’s 26-man squad and will captain Argentina away to arch-rivals Brazil in Belo Horizonte on Nov. 10 and at home against Colombia in San Juan five days later.
Argentina have slipped down the South American group standings to fifth after a shock 1-0 home defeat by Paraguay and 2-2 draws with Peru and Venezuela, all without Messi.
They have 16 points from 10 matches, five less than leaders Brazil with Uruguay second on 20 and Ecuador and Colombia on 17. The top four go through to the 2018 finals in Russia with the fifth qualifying for an intercontinental playoff for another berth.
Valencia winger Enzo Perez, who last played for Argentina in a 1-0 away win over Colombia in a qualifier last November, has been recalled.
There were first call-ups for right back Julio Buffarini, a key member of the San Lorenzo side Bauza coached to the Copa Libertadores title in 2014 who now plays for Sao Paulo in Brazil, and Racing Club midfielder Marcos Acuna.
Bauza has dropped Manchester United defender Marcos Rojo, Tottenham Hotspur’s Erik Lamela and midfielder Matias Kranevitter of Sevilla.
