After rookie left tackle Braxton Jones responded to the challenge of facing Robert Quinn in practice, the fifth-round pick from Southern Utah is in line for a similar challenge against 49ers Pro Bowl defensive end Nick Bosa.
Bears offensive coordinator Luke Getsy would not commit to a starting offensive line with the opener against the 49ers still 13 days away. But Jones figures to be the starter after a strong preseason that confirmed an impressive introduction in the offseason program.
Jones would be the first rookie to start in Week 1 at left tackle since second-round pick Troy Auzenne in 1992.
