Weiss said the team would re-evaluate Rosario before Friday's game. Backup catcher Michael McKenry replaced Rosario on Thursday, and Weiss said it was too early to know whether the injury would necessitate the callup of another catcher.
"It doesn't seem like it's too serious, but it was bugging him pretty good," Weiss said.
This is the latest in a series of maladies for Colorado's catcher. Rosario dealt with nagging issues with his left hand early in the season and spent time on the disabled list in May because of a viral infection. He was also a late scratch on June 7 because of illness.
Rosario is batting .246 with eight home runs.
