Raiders cornerback Nnamdi Asomugha sprained his ankle in Sunday's win over the Seahawks and is expected to have an MRI. X-rays were negative and Oakland doesn't yet know the severity of the injury. Asomugha went down defending a deep pass to Seahawks wideout Golden Tate in the fourth quarter Sunday.

Cowboys cornerback Terence Newman hasn't practiced all week due to a rib strain, but he expects to play on Sunday against the Jaguars. Newman suffered the injury in Monday night's loss to the Giants while making an interception.

Vikings quarterback Brett Favre is questionable for Sunday's game against the Patriots. Favre lobbed passes in Friday's practice as he hobbled around the field because of two fractures in his ankle. Minnesota coach Brad Childress said he "probably will" wait until the last hours before kickoff to decide whether Favre or Tarvaris Jackson will start.

Panthers running back DeAngelo Williams is doubtful for Sunday's game against the Rams. Williams has missed his third straight practice with an unspecified foot injury. He is Carolina's top rusher with 361 yards on 87 carries.

Cowboys owner Jerry Jones says there is a chance that Tony Romo could miss the remainder of the season. Romo broke his collarbone on Monday night and will miss six-to-eight weeks. Dallas is 1-5 and it appears likely that they will be eliminated from the postseason before Romo is ready to return. "We'll just see what the circumstances are at that time," Jones said. "We'll see how well we're playing. They remember what you do in November. That is an old college saying that my coach used to say all the time. "If we have an opportunity to have a good taste by the team playing well, have a good taste in our mouths ... then even if you're out of an opportunity to be in the playoffs, you want to be playing good."

Saints running back Reggie Bush has been on the practice field this week, but his return for this Sunday's game against the Steelers is still "doubtful." Bush broke his leg in Week 2 and has been out since.

Vikings quarterback Brett Favre won't rule himself out for Sunday's game against the Patriots. "I'm willing to give it a try," said Favre, who suffered two ankle fractures on Sunday night against the Packers. Favre wore a large, gray walking boot on his left leg for his regular news conference on Wednesday. His NFL-record streak is at 291 consecutive games started, 315 including the playoffs.

Vikings quarterback Brett Favre has consulted with the doctor who performed the offseason operation on his oft-injured left ankle, according to a report on NFL.com. Favre, 41, suffered a stress fracture in his left ankle and an "avulsion" fracture in his left heel bone in the Vikings' 28-24 loss Sunday night at Green Bay. Dr. James Andrews did arthroscopic surgery on Favre's left ankle last spring to remove scar tissue and bone spurs.

Broncos rookie cornerback Parrish Cox suffered a head injury in the third quarter of the team's loss to the Raiders on Sunday. Cox couldn't recall any of the details from the game. He clearly remembers the night before and then coming to in the trainer's room. "I woke up and asked what the score was and they told me, 'A lot to a little,' " Cox said. "That was kind of shocking to me -- I don't remember nothing."

The Bengals have placed cornerback Adam "Pacman" Jones on the injured reserve because of a neck injury that may require surgery. Jones has a herniated disk in his neck. "It looks very promising for him," agent Tom Hunter said. "Do not ever count this man out. He is going to be back."
