The Cubs transferred Rivas (finger) from the 10-day injured list to the 60-day IL on Sunday, Russell Dorsey of the Chicago Sun-Times reports.

Rivas had already been ruled out for the season after landing on the 10-day IL on Sept. 21 with an injury to his right middle finger. His move to the 60-day IL frees up a spot on the 40-man roster for minor-league catcher Tyler Payne, who will serve as the backup to starter Erick Castillo in Sunday's season finale in St. Louis. The transaction won't affect Rivas' recovery timeline, as the 25-year-old rookie is expected to be in line for a relatively normal offseason.
