Harris rushed for 73 yards on 11 carries and added an 11-yard catch in Sunday's loss to the Lions.
The 73 rushing yards were a career high for Harris, who has spent time with six teams this season. Before any trash-to-treasure cliches are spoken, it is important to note that the 49ers' stable of backs has been a menagerie of mediocrity since Carlos Hyde got hurt, with limited stability in roles. Sunday's performance could propel Harris into a sizable role in Week 17, but it is more likely that the team will stick with the hot hand against the Rams as they look to see what talent they have heading into 2016.
