What happened: Pro Football Focus highlighted the interior clash between guard Quenton Nelson and defensive tackle Jeffery Simmons as a premier matchup for Week 9. The two previously squared off in Week 6 before both players were dealt to new franchises in late October.

Why it matters: The Seahawks plan to start Nelson at left guard against Chicago on Monday night. Simmons, who was acquired by the Bears for two first-round picks, lines up opposite him along the interior defensive front.

What to watch: Nelson and Simmons will face each other when the Seahawks visit the Bears on Monday Night Football.
