Cron was scratched from the lineup ahead of Saturday's game against the Marlins.
The Rockies have yet to announce a reason for Cron's absence. It could be injury or illness, though at this time of year, it could also indicate that a trade is coming. Cron owns a subpar 92 wRC+ this season but could still be attractive as a rental, especially as he's been in great form recently, homering four times in his last five games. Michael Toglia will take over for him at first base.
