Chicago Bears wide receiver Brandon Marshall reportedly is out for the season after suffering two broken ribs and a lung injury Thursday night in the Bears’ 41-28 loss to the Dallas Cowboys.

The Bears said Marshall was still in a Chicago hospital Friday.

While making a fourth-down catch in the second quarter, Marshall was kneed in the back by defensive back Barry Church. Marshall was taken by ambulance to a local hospital, where doctors reportedly treated him for a collapsed lung.

The Bears already have ruled him out for their game next week against the New Orleans Saints, and NFL.com and ESPN.com both have reported he will miss the rest of the season.

Marshall, 30, has 61 catches for 721 yards and eight touchdowns this season.

—The NFL reportedly is investigating whether the Dallas Cowboys concealed an injury to quarterback Tony Romo.

After Dallas’ 41-28 win over the Bears on Thursday night, Romo said he has been playing with a broken rib since early in the season. But the team had not listed the injury on the weekly injury report.

If the Cowboys failed to list an injury they knew about, they could be subject to a fine. The New York Jets were fined $125,000 in 2009 for failing to list quarterback Brett Favre’s torn biceps tendon for the final month of the 2008 season.

Romo has been listed on the injury report all season because of his back, which was surgically repaired in the offseason. He also suffered transverse process fractures when he took a knee to the back against the Washington Redskins on Oct. 27.

—Minnesota running back Adrian Peterson’s appeal of his suspension reportedly will be resolved next week.

Peterson’s appeal was heard this week by league-appointed arbitrator Harold Henderson, who is expected to rule by midweek, the St. Paul Pioneer Press reported Friday.

Peterson was suspended for the rest of the season by commissioner Roger Goodell on Nov. 18, after Peterson failed to attend a disciplinary hearing regarding his alleged violation of the NFL’s personal conduct policy.

Peterson was indicted in September on felony charges of reckless or negligent injury to a child after Texas authorities said he hit his 4-year-old son with a switch. He pleaded no contest to misdemeanor reckless assault on Nov. 4 and was ordered to pay a $4,000 fine and perform 80 hours of community service.

—The Tampa Bay Buccaneers released offensive coordinator Jeff Tedford from his contractual obligations in order to allow him to pursue other opportunities.

The 53-year-old Tedford took an indefinite leave from the Bucs in September after undergoing a coronary angioplasty prior to the season. In his absence, quarterbacks coach Marcus Arroyo has run the offense.

Tedford was coach at California from 2002 through 2012. He was known for his work with quarterbacks, most notably Aaron Rodgers when he was at Cal.

—The St. Louis Rams wrapped up one of their core special teams players Friday with the signing of punter Johnny Hekker to a six-year contract extension that goes through 2020.

The deal is worth a reported $18 million and includes $9 million guaranteed, $750,000 of that in the form of a signing bonus.

Hekker, who signed a three-year contract as an undrafted free agent in 2012 that included a $10,000 signing bonus, was scheduled to become a restricted free agent in 2015. His salary this year is $570,000.

Hekker set an NFL record with a net average of 44.2 yards last season and his career net of 41.9 is the third-best in the league since he arrived. His 41.4-yard net this season is sixth in the NFL.

—Arizona Cardinals running back Andre Ellington and safety Tyrann Mathieu will miss Sunday’s game against the Kansas City Chiefs.

Wide receiver Larry Fitzgerald will be a game-time decision for the Cardinals, who are 9-3 and trying to snap a two-game losing streak. Fitzgerald has missed the last two games with a knee injury.

Ellington missed his third straight practice Friday because of a hip injury. Arians said Stepfan Taylor will start at running back. The Cardinals released recently signed Michael Bush on Friday as linebacker Matt Shaughnessy returned from injured reserve.

—Minnesota Vikings running back Jerick McKinnon was ruled out for Sunday’s game against the New York Jets with a lower back injury.

The Jets ruled out tight end Jace Amaro (concussion) and defensive end Muhammad Wilkerson (toe). They both were inactive for Monday night’s game against the Miami Dolphins.

McKinnon did not practice all week with the back injury, which kept him out of last Sunday’s win against the Carolina Panthers. He leads the Vikings in rushing yards (538) and carries (113).

—Tennessee Titans wide receiver Kendall Wright has a cracked bone in his right hand but he could still play Sunday against the New York Giants.

Wright suffered the injury when he slipped at Wednesday’s practice and didn’t participate in Thursday’s practice. Wright was spotted with a splint on his hand Thursday.

Wright, the team’s leading receiver with 51 catches and five touchdowns, is considered day-to-day.

—Carolina Panthers running back DeAngelo Williams will not play Sunday against the New Orleans Saints, but tight end Greg Olsen has a good chance to go, coach Ron Rivera said Friday.

Olsen, who leads the Panthers with 61 catches (778 yards and five touchdowns), is listed as questionable with a knee injury.
