Anderson (knee) is expected to be activated and will likely will be involved in what's expected to be a bullpen game Sunday, Nick Groke of The Denver Post reports.
Tyler Chatwood led the charge in the last bullpen game Tuesday, and this seems to be a similar setup, with Anderson expected to log time as Colorado pieces together the game with several arms. Anderson doesn't appear to be in a role that'll offer any fantasy value the rest of the season.
