Adam Schefter is reporting that Hardesty is done for the season:

Further tests revealed what initial tests showed: Browns rookie RB Montario Hardesty has a torn ACL. Out for year.

Bad news for Hardesty is great news for Jerome Harrison owners, who will likely have a solid RB2 for the price of a 7th-9th round pick. Peyton Hillis has played well and was productive in Denver, so he will probably get some touches to keep Harrison fresh. He could also vulture some goal line work.

Still, Harrison is looking like a great value in the middle rounds and is another reason why it’s a solid strategy to grab a couple of premier WRs in the first three rounds and worry about shoring up the RB position later.
