Choo has a strained hamstring and Stubbs has a sprained toe.
Joey Gallo and Jared Hoying were called up from Triple A to take the empty spots on the roster.
Gallo is ranked by MLB.com as Texas’s top prospect and the No. 7 prospect in baseball. He batted .204 with a .717 OPS in 36 major league games last season.
Choo was making his return from a strained right calf injury, but was pulled from Friday’s 2–1 victory with a hamstring strain in the bottom of the third inning, as he scored on a double by Prince Fielder. Choo had been on the disabled list since April 10.
In his third season with the Rangers, Choo is hitting .188 with three hits and just one RBI in his six games of action. Stubbs was released by the Braves earlier this month and picked up by Texas. He batted .267 in his first 10 games with the Rangers.
