Zach Miller underwent emergency surgery on Sunday in an effort to save his injured left leg.

Miller dislocated his knee in the third quarter of Sunday's game against the Saints. Sources told Mortensen that Miller's dislocated knee is considered "more significant" than a regular dislocation, which is a serious injury.

Vascular surgeons were called in to repair Miller's leg, which includes grafting tissue from the other leg to repair the damaged artery.

The Chicago Bears have traded a conditional seventh round pick in 2018 to the Los Angeles Chargers for wide receiver Dontrelle Inman.

Inman, 28, has appeared in just four games this season with two receptions for 9 yards. Last season, Inman caught 58 passes for 810 yards and four touchdowns.

The Bears, who lost top receiver Cameron Meredith for the season in August, are in need of help at wide receiver as, other than Kendall Wright, the team's production at the position has been slim.

Danny Trevathan has had his two-game suspension trimmed to one game after an appeal.

The Chicago Bears linebacker was disciplined for a hit last Thursday night that sent Green Bay Packers wide receiver Davante Adams to the hospital.

Adams was taken off the field on a stretcher with about 4 minutes left in the third quarter Thursday after he was hit in the head during a tackle by Trevathan.

Trevathan was called for an unnecessary roughness penalty but was not ejected.

"I regret the level I hit him at," Trevathan said. "But you got to understand I had momentum, and I was just trying to make a play."

The Chicago Bears will start Mitchell Trubisky beginning with their Week 5 game on Monday night against the Minnesota Vikings.

Mike Glennon turned the ball over four times in Week 4. Glennon is earning $16 million in guaranteed salary in 2017.

Trubisky was the second overall pick in the 2017 NFL Draft.

Trubisky won Chicago's primary backup job in Week 1, beating out veteran Mark Sanchez.
