Amador will be placed on the injured list Friday with a right oblique strain, Patrick Lyons of JustBaseball.com reports.
Amador's move to the injured list comes as Brendan Rodgers gets activated from the IL, meaning the rookie's playing time was coming to an end regardless. The 21-year-old Amador appeared in 10 games with the Rockies but struggled to a .171/.194/.200 slash line with a stolen base. While it's unclear how long he'll be sidelined, there is optimism that his recovery will be quick.
