The duo will help bolster the Supporters' Shield winner's depth in 2017.
FC Dallas has announced the signings of Argentine right back Hernan Grana and Venezuelan midfielder Carlos Cermeno.
Grana joins on a season-long loan from Club Atlético All Boys, with FCD retaining the option to purchase the defender at the end of the season. The right back has spent over 11 seasons in the Argentine top flight, and also played seven matches for the Columbus Crew in 2015 before returning to Argentina due to homesickness.
