Trammell was removed from Monday's game against the Guardians in the fourth inning due to an apparent lower-body injury, Matt Kawahara of the Houston Chronicle reports.
Trammell appeared to sustain the injury while running to third base and left the field with a trainer shortly after. He went 1-for-1 with a walk prior to being replaced by Cam Smith in the outfield. The Astros should have an update on Trammell's injury once he undergoes more tests.
