Steelers' Najee Harris: Nursing arm injury after Week 3 win

Harris was wearing a sling around his right arm/elbow in the Steelers' locker room Monday, Alan Saunders of SteelersNow.com reports.

Harris didn't substitute out due to an apparent injury during Sunday's 20-10 win over the Chargers, in which he rushed 18 times for 70 yards including Pittsburgh's final carry. He also caught all five of his targets for 16 yards, and Steelers coach Mike Tomlin didn't mention an injury to Harris in his postgame press conference. Further clarity on Harris' health may not arrive until Wednesday, when Pittsburgh's first official injury report of Week 4 is revealed. If healthy, Harris will stand to continue handling a workhorse role Sunday on the road against Indianapolis.
