Steelers QB Ben Roethlisberger will undergo surgery Monday morning on his left knee, Ron Cook of the PG/937 The Fan first reported Sunday night.

Roethlisberger has been diagnosed with a torn meniscus and the procedure will be a cleanup that will sideline Roethlisberger from anywhere of 2-6 weeks.

Roethlisberger will be ruled out for Sunday’s game vs the Patriots. The Steelers have a bye in Week 8.
