Donald Brown (knee) was downgraded to out in Thursday's practice.
Brown was "full" on Wednesday. This would normally be cause for alarm, but it's the same pattern Brown followed two weeks ago. Brown didn't practice last week with the Colts on a short week, but split time evenly with Vick Ballard in Indy's Thursday evening win. Brown's status will certainly be worth double-checking on Friday, but for now there's no reason to believe he won't be ready to split the load with Ballard against the Patriots.
So what you're saying is, this weekend both backs are worthless. lol
