Cron (back) has yet to resume baseball activities, Patrick Saunders of The Denver Post reports.
Cron has already missed a week of action with lower-back spasms but remains limited to just receiving treatment to this point. He'll be eligible for activation from the injured list later this week, but it sounds like it could be a while longer than that. Mike Moustakas and Michael Toglia have been handling first base in Cron's absence.
