Bouchard was removed from Saturday's game against the Nationals with back tightness, Luke Zahlmann of The Denver Gazette reports.
Bouchard awkwardly fielded a ball in the third inning and was replaced in right field by Jake Cave to start the fourth. Bouchard was activated from the 10-day IL on Wednesday with an ankle injury, so Saturday's back issues are new. The Rockies will have a team day off Monday after closing their series with the Nationals on Sunday.
