Steelers' Najee Harris: Sits out practice

Harris (knee) didn't practice Wednesday, Brooke Pryor of ESPN.com reports.

Harris was listed as a limited participant at Tuesday's walkthrough, but Wednesday's absence is most likely a case of load management for the running back ahead of Saturday's pivotal game against the Ravens. He's frequently sat out practice in recent weeks but has yet to miss a game this season and is coming off his best rushing performance of the campaign -- a 122-yard, two-touchdown effort in a Week 17 win over the Seahawks.
