CAM NEWTON will not play Sunday against Tampa Bay while recovering from an automobile crash that left him with two fractures in his lower back.

Panthers coach Ron Rivera confirmed yesterday that Derek Anderson will start and Joe Webb will be his backup.

"I won't expose him," Rivera said of Newton. "I don't want to put him in a bad position."

Newton was discharged from the hospital earlier yesterday, a day after he was injured when his truck crashed and overturned in a two-vehicle accident. Charlotte-Mecklenburg police issued no citations for the accident.

Newton was not at the team's facility yesterday, though Rivera said he is expected to be in today, and his playing status will be re-evaluated next week.

The coach said he met with Newton on Tuesday at the hospital and, "in true Cam fashion, he was disappointed for his teammates. He feels like he is letting us all down."

Panthers spokesman Charlie Dayton said yesterday that Newton is stiff and sore, but otherwise "his spirits were high."

A police report states that Newton was driving when a car driven by Nestor Pellot Jr., 46, of Fort Mill, S.C., pulled out in front of Newton, causing his vehicle to flip. The report said Pellot didn't see Newton's truck at first and when he did, he tried to avoid a collision. The report does not place blame on either driver. However, the report lists two witnesses who said Pellot pulled out in front of Newton, causing $9,000 damage to the quarterback's 1998 Dodge truck. Pellot's 2013 Buick suffered $4,000 damage.

Like Newton, Pellot was taken to the hospital, but his injuries are unknown.

Noteworthy

* NFL owners unanimously approved changes to the personal-conduct policy, but commissioner Roger Goodell will retain authority to rule on appeals. A special counsel for investigations and conduct will oversee initial discipline, Goodell said.

"This will be a highly qualified individual with a criminal-justice background hired as soon as possible for the newly created position," Goodell said. "The person will oversee our investigations and decide the discipline for violations of the policy."

The commissioner also may appoint a panel of independent experts to participate in deciding an appeal.

A more extensive list of prohibited conduct will be included in the policy, as well as specific criteria for paid leave for anyone charged with a crime of violence, including domestic violence.

* Houston placed top overall draft pick Jadeveon Clowney on the injured reserve, 2 days after he had microfracture surgery on his right knee. The surgery was the second this season for the outside linebacker. He had arthroscopic surgery on the same knee after being injured in Week 1. He played three games since the first procedure but continued to struggle with pain and swelling in his knee before deciding to have the second surgery.

* Washington coach Jay Gruden didn't name who his starting quarterback will be, in part to try to keep the firestorm over his choice from erupting, as was the case earlier this season. Colt McCoy, who started the last two games, was back at practice after leaving Sunday's game with a sprained neck.

* Minnesota placed former Penn State linebacker Michael Mauti on injured reserve and signed tackle Carter Bykowski off San Francisco's practice squad. Coach Mike Zimmer said Mauti, primarily a special-teams player, needed minor knee surgery.

* Jacksonville placed leading rusher Denard Robinson on injured reserve with a midfoot sprain.

* Former Buffalo star linebacker Darryl Talley accepted nearly $153,000 in donations generated in 2 weeks during an impromptu Internet fundraiser that popped up after revelations of health problems he considers side effects from his hard-hitting play.
