Siemian will not practice Wednesday due to an oblique injury, Jason Lieser of the Chicago Sun-Times reports. Siemian injured his oblique during pre-game warmups ahead of Sunday's 31-10 loss to the Jets, though he did manage to play through the issue and start, throwing for 179 yards, one touchdown and one interception. Justin Fields (shoulder) is practicing in a limited capacity Wednesday and hasn't been ruled out for Week 13's divisional matchup against the Packers, but his status appears truly uncertain, so the Bears could be taking a cautious approach to Siemian's health. Nathan Peterman is available as a No. 3 option for Chicago, and the team also signed Tim Boyle off Detroit's practice squad Wednesday.
