Seahawks vs. Bears live updates: Jeffery Simmons makes Chicago debut in key NFC clash on 'MNF'

Seahawks coach Mike Macdonald confirmed this week that Quenton Nelson will start at left guard just six days after the team traded for him. Nelson arrived by way of the Indianapolis Colts in exchange for a 2027 third-round pick and 2028 fifth-rounder and could help jumpstart one of the NFL's least efficient rushing offenses.

Nelson will remain at left guard, where he played in Indianapolis. Keeping him at his most natural position requires the Seahawks to move Grey Zabel over to right guard. There will also be a third change on the offensive line with starting left tackle Charles Cross ruled out with an ankle injury. Josh Jones will step into the lineup at that spot.

This is the fourth consecutive game Kyle Monangai has missed due to turf toe and a thumb issue. Roschon Johnson will continue to work as the No. 2 running back behind D'Andre Swift.

Jalen Milroe will act as Seattle's backup quarterback for the second consecutive week. This is a recent shakeup in the signal-caller unit after Drew Lock opened the year as the No. 2 option and made one start when Sam Darnold was out with a glute injury.

The start of the Jeffery Simmons era on the Bears' defensive line is nearly here. The three-time All-Pro defensive tackle, who Chicago acquired from the Titans in exchange for two first-round draft picks and a Day 3 pick swap, is with the team and will suit up against the Seahawks.

Coach Ben Johnson said this week that Simmons may not play quite as much on Monday as he did in each of his previous games this season as he transitions to a new defense, but "he has certainly shown the ability to carry a load." Johnson also said he anticipates Simmons picking up the defensive system quickly and that he is encouraged by what he has seen thus far from his new weapon.
