Pats LB coach Johnson had quad surgery

Patriots linebackers coach Pepper Johnson underwent surgery this past week for a torn quad muscle that will force him to be on crutches on the sideline for today's game against Indianapolis, a league source to ESPN NFL Insider Adam Schefter.

Johnson tore his quad during practice last week and was in enough discomfort that he underwent surgery early in the week, forcing him to spend time away from the Patriots training facility while the team was prepping for today's game against the Colts and the Thanksgiving night game versus the divisional-rival Jets.
