Remember, he hasn't exactly been a fantasy superstar since Week 2, and he was already sharing time with Daniel Thomas. He injured his knee in Week 3 against the New York Jets, and he hasn't been the same since.
Reggie Bush was already playing less snaps than Daniel Thomas. Then he got benched after a first-quarter fumble today: bit.ly/lmwUxj— Adam Levitan (@adamlevitan) November 11, 2012
This was Bush's second lost fumble in three weeks, and given the fact that Thomas has already been vulturing his touchdowns and touches, it seems likely that Bush's production will continue to be unreliable.
The Dolphins will continue to use him as a complementary back to Thomas, and he isn't likely to have any more 100-plus-yard, two-touchdown games this season.
That said, the next team on the schedule for the Dolphins is the Buffalo Bills—the No. 31-ranked rushing defense in the NFL. Until we hear word that Bush has been permanently demoted, he's worth keeping in your starting lineup as a flex.
The truth of the matter, though, is that Bush has lost any appeal as a RB1 or RB2, and unless you're in a deep league, you should at keep him on your bench for now, at least—if not get rid of him altogether.
