Rojas (back) recently received a cortisone injection but was included on the Dodgers' roster for the NLCS, Alden Gonzalez of ESPN.com reports.
The club hasn't provided an official update regarding the 27-year-old availability, but his inclusion on the NLCS roster -- and Hyeseong Kim's exclusion -- is a good indication that Rojas is fine. The utility infielder appeared in two games during the NLDS, going 1-for-4 with a double and a strikeout.
