Trent Richardson isn't making the trip to New England

for 'personal reasons'.

He's slipped to, at least, 3rd on the Colts depth chart, and they have another back who plays STs. It looks like he's been active pretty much every game this season, but has fallen fully out of favor and isn't even starting anymore (he did start 12 games).

Colts pay him $3.2M whether he with them or not (fully guaranteed, no offset language), but my money says they'd rather have a roster spot than a guy making that money and maybe playing STs.
