Steelers' Alex Highsmith: In concussion protocol

Ian Rapoport of NFL Network reports Friday that Highsmith has entered the NFL's concussion protocol following Thursday's 21-18 loss to the Patriots.

Highsmith sustained what was reported as a neck injury in the first half of Thursday's loss and did not return. The good news for Highsmith and the Steelers is that he has over a week to clear the NFL's five-step concussion protocol and be ready to play in Week 15 against the Colts.
