​New England Patriots running back Corey Kiner may be a worthwhile waiver-wire addition for fantasy football team managers ahead of Week 1 in the event that TreVeyon Henderson is unable to play against the Seattle Seahawks.Henderson is dealing with an ankle injury that is threatening his chances to play in the season opener against Seattle. A potential Henderson absence will leave Rhamondre Stevenson in line for the largest role in New England’s offensive backfield, but Kiner is in line to be the backup behind him in the lineup. That potential opportunity makes him an intriguing option, particularly for managers playing in deeper leagues.Kiner may end up benefitting from additional carries and potentially earn work in short-yardage or goal-line situations. His fantasy value will largely depend on how New England divides the workload and how the game unfolds.The Seahawks have a strong defense against the run. Leonard Williams and Byron Murphy clog up the middle while DeMarcus Lawrence and Derick Hall cause disruption on the outside.Still, running back opportunities are liable to change quickly when injuries strike, making Kiner a player worth monitoring before kickoff. If Henderson is ruled out, fantasy managers looking for a low-cost addition will have reason to consider Kiner as a pickup with the potential to become useful in Week 1.For managers lacking running-back depth, Kiner may shape up to be a smart pregame addition.Follow Patriots Wire on Twitter and Facebook.This article originally appeared on Patriots Wire: Who fantasy owners can target if Patriots RB TreVeyon Henderson is out
