What happened: Guard Quenton Nelson and defensive tackle Jeffery Simmons make their team debuts Monday night when the Seattle Seahawks host the Chicago Bears. Both former AFC South linemen were acquired last week, with Seattle adding Nelson from the Indianapolis Colts and Chicago securing Simmons from the Tennessee Titans.

Why it matters: The matchup creates an immediate head-to-head clash in the trenches after an interior line rematch was set across new conferences. Chicago enters at 5-2 in the NFC playoff picture, while 4-3 Seattle looks to defend home field in the conference standings.

What to watch: Kickoff is scheduled for Monday at 8:15 PM ET in Seattle.
