Leno Jr. signed a four-year extension with the Bears on Wednesday, Marc Sessler of NFL Network reports.
The Bears have the left side of their offensive line locked down for years to come, as both Leno Jr. and left guard Kyle Long are now under contract through the 2021 season.
The Bears have listed the following players as inactive for Sunday's season finale against Minnesota: Jimmy Clausen (concussion), Robbie Gould (right quadriceps), Al Louis-Jean (hamstring), Chris Conte (back), Charles Leno, Austen Lane and Brandon Dunn.
The Bears have listed LB Lance Briggs, LB Jon Bostic, OL Jordan Mills, S Danny McCray, CB Terrance Mitchell, DB Ahmad Dixon and OL Charles Leno, Jr. as inactive Week 8 against the Patriots.
The Bears will be without a couple notable defensive players. Both Briggs and Bostic will need more time to recover, leaving the team thin at linebacker. Jordan Mills will also miss the contest, hurting the offensive line.
The following players were ruled active for the Bears at home against Miami in Week 7: Lance Briggs, Jon Bostic, Chris Conte, Terrance Mitchell, Ahmad Dixon, Charles Leno and Trevor Scott.
Bears center Roberto Garza (ankle) has been ruled out for the Sunday game at Carolina. He had been deemed doubtful. The same fate also has befallen cornerback Sherrick McManis (quad). Safety Ahmad Dixon (hamstring), tackle Jermon Bushrod (knee/ankle), linebacker Shea McClellin (hand) and nose tackle Jeremiah Ratliff (concussion) are also inactive.
Their lone healthy scratch is tackle Charles Leno.
The Bears declared linebacker Shea McClellin (hand), defensive tackle Jeremiah Ratliff (concussion), center Roberto Garza (ankle), cornerback Sherrick McManis (quad), guard Matt Slauson (ankle), defensive end Trevor Scott (foot) and offensive tackle Charles Leno inactive for Monday's game at the Jets.
The Bears declared these players inactive for Sunday night's game in San Francisco: wideout Josh Morgan (groin), linebacker Khaseem Greene, center Roberto Garza, guard Matt Slauson, offensive tackle Charles Leno and defensive ends David Bass and Cornelius Washington.
The Bears have declared the following players inactive for Sunday's season opener against the Bills: linebacker Khaseem Greene, quarterback David Fales, defensive ends David Bass and Cornelius Washington, offensive tackle Charles Leno, cornerback Kelvin Hayden and fullback Tony Fiammetta.
Greene played in 15 games last season as a rookie, making four starts. Fiammetta was questionable to play due to a hamstring injury after being limited at practice all week.
The Bears agreed to terms with offensive tackle Charles Leno, safety Brock Vereen and quarterback David Fales. Four of Chicago's eight draft picks are under contract.
The Bears added some offensive line depth late in the draft Saturday, selecting offensive guard Charles Leno out of Boise State with the 246th overall pick.
