Patriots RB Rhamondre Stevenson has been diagnosed with a high-ankle sprain, ESPN's Adam Schefter reports. A source tells Schefter that Stevenson is expected to miss "a few weeks." High-ankle sprains generally cost RBs 4+ games, so don't be surprised if Stevenson misses the rest of the season. He's droppable in most fantasy leagues without an IR spot. Stevenson's absence will leave Ezekiel Elliott as New England's clear lead back -- in a true test of whether pure volume can support a fantasy RB. New England has RBs Jamycal Hasty and Ty Montgomery behind Elliott on the active roster, with RB Kevin Harris on the practice squad.
