Aaron Rodgers plans to play in Week 13 against the Chicago Bears despite a rib injury.

"I got good news with the scans yesterday," Rodgers said Tuesday on "The Pat McAfee Show." "So, I plan on playing this week."

Rodgers initially feared he might have a punctured lung, but that was quickly ruled out. 

The San Francisco 49ers will be without Elijah Mitchell for 6-8 weeks because of a knee injury.

Mitchell left Sunday's win over the New Orleans Saints with the injury. The Niners originally thought the running back had an MCL sprain that would sideline him for just 2-4 weeks.

"It wasn't the news we were looking for," Kyle Shanahan said.

Mitchell, who set a franchise rookie record with 963 yards rushing last season, only returned from an injured reserve stint on Nov. 12. He injured his knee in the season opener and missed seven games.

"He's pretty disappointed," Shanahan said. "Everyone knows how good Elijah's been, how hard he's worked to get back from his last one and how good he's been playing since he came back. To be right back there, I know he was real down on it. He's had some real bad luck. He got rolled up on and it was a bad position for him to be in."

Matt LaFleur has made it clear that Aaron Rodgers will remain the starting quarterback for the Green Bay Packers as long as he's healthy.

Already dealing with a fractured thumb, Rodgers left the Packers' loss to the Philadelphia Eagles with a rib injury on Sunday.

Rodgers left in the third quarter with pain and trouble breathing. He underwent additional tests on Monday. LaFleur was vague about the results.

"Sometimes there's stuff that doesn't show up on all the scans," LaFleur said. "All I can tell you is he's feeling a little bit better."

Jordan Love was impressive in relief, going 6-for-9 with 113 yards and a touchdown. Green Bay scored 10 points on his two drives.

"I don't think that's what we're arguing here," LaFleur said. "It's just, we've got a lot of faith, quite frankly, in both those guys. But you know, Aaron's the starting quarterback. He's battled through a lot throughout the course of his career. It's pretty well documented, and I think he's been able to play at a pretty high level through a lot of different situations. So again, we'll take it one game at a time and make the best decision moving forward."

The San Francisco 49ers believe Elijah Mitchell suffered a sprained medial collateral ligament in his left knee on Sunday afternoon.

Mitchell returned from a sprained MCL in his right knee just two weeks ago.

The running back is scheduled for further testing on Monday. Mitchell was originally designated as questionable to return, but the Niners ruled him out near the end of the quarter.

Aaron Rodgers left the Green Bay Packers' 40-33 loss to the Philadelphia Eagles on Sunday night with an injury to his ribs.

He left in the third quarter and did not return. The quarterback was already dealing with a broken thumb.

Rodgers will undergo an MRI on Monday, and if tests come back negative, he intends to play in Week 13.

The Los Angeles Rams have lost Allen Robinson for the remainder of the season as he will require foot surgery.

Robinson was having "some soreness in his foot" during the week. After an injection to "see if he could push through," a CT scan revealed a stress fracture on the navicular bone in one foot, Sean McVay said.

Robinson, who signed a three-year, $46.5 million contract with the Rams in March, has 33 catches for 339 yards and three touchdowns this season.

The Rams are already without Cooper Kupp due to a knee injury.

The Los Angeles Rams are uncertain when or if quarterback Matthew Stafford will return this season, league sources told ESPN.

Stafford is out Sunday against the Kansas City Chiefs because of a strained neck and two recent trips to the concussion protocol. He suffered one concussion earlier this month, and the Rams never could prove he suffered a second concussion even though he was in the protocol a second time.

Tampa Bay Buccaneers running back Leonard Fournette has been ruled out for Sunday's game against the Cleveland Browns.

Fournette had suffered a hip pointer during the Buccaneers' previous game two weeks ago in Munich, and the team had taken a cautious approach to his playing on Sunday.

Chicago Bears quarterback Justin Fields, who is dealing with a separated left shoulder with partially torn ligaments, is not expected to play Sunday at the New York Jets, a source told ESPN's Adam Schefter.

The Bears are expected to start Trevor Siemian at quarterback, and the team also promoted Nathan Peterman from the practice squad Saturday to serve as the backup at that position.

Chicago Bears quarterback Justin Fields said Wednesday that he is dealing with an injury to the acromioclavicular joint in his left shoulder and will evaluate how he feels later this week before determining whether he'll play against the New York Jets.

"It's a separated shoulder with partially torn ligaments," Fields said, describing his injury. "Basically, like an AC joint. That's my understanding of it."
