The move is retroactive to July 4, so Infante will be eligible for activation after the All-Star break.
Infante hasn't played since last Wednesday, when he was hit hard by Toronto's Colby Rasmus, who was sliding into second base.
Tigers manager Jim Leyland says he expects Infante to be OK after the break. Infante is hitting .309 with six homers and 27 RBIs.
Perez started in his place in the series opener against the Chicago White Sox on Tuesday night. He made his major league debut last month, playing in two games for the Tigers.
