New York Jets quarterback Chad Pennington and Buffalo Bills linebacker Takeo Spikes are out for the season after being injured in games Sunday.
A person with knowledge of Pennington's injury told The Associated Press on Monday that he has a torn rotator cuff — the same injury he suffered last year and had offseason surgery to repair. The person, who declined to be identified because the team had not made an official announcement, said an MRI exam revealed the injury.
Spikes, a leader of Buffalo's defense, will be sidelined with a torn right Achilles' tendon.
Pennington was hurt in Sunday's 26-20 overtime loss to Jacksonville.
Backup Jay Fiedler also damaged his shoulder Sunday and will be sidelined, leaving third-stringer Brooks Bollinger to play quarterback against Baltimore this weekend.
Pennington and Spikes were among several NFL stars injured on Sunday, including Patriots safety Rodney Harrison, Eagles kicker David Akers and Bengals tackle Willie Anderson.
On Monday night in Denver, Broncos cornerback Champ Bailey left the field limping and grabbing his left hamstring in the second quarter against the visiting Kansas City Chiefs after tackling fullback Tony Richardson. Bailey was grimacing and yelped in pain as he was helped off the field, and Broncos officials said he would not return.
Broncos receiver Rod Smith also left the game and didn't return after getting hit in the head early in the fourth quarter. The team said he had a concussion.
Spikes, an eight-year NFL veteran in his third season with Buffalo, developed into the team's physical and inspirational leader. He was hurt in the second quarter while pressuring quarterback Michael Vick. Spikes remained face down on the field a few feet in front of Vick, then slammed his helmet to the ground when he rolled over and grimaced as he tried to kneel. He required help getting to the sideline, unable to place much weight on his right foot. He was in tears when he was carted to the training room.
"It's devastating," safety Troy Vincent said. "But we can't lose the swagger. ... We're just going to have to pick up the pieces and keep rolling. No player wants that to happen to them, but that's part of the game."
Angelo Crowell will replace Spikes, who was lured from Cincinnati in March 2003 with a six-year, $32 million contract.
The Eagles replaced distractions with injuries. Akers probably will miss Philadelphia's game at Kansas City next week because of a torn hamstring, while Donovan McNabb's status is uncertain.
Akers, who collapsed to the ground in pain after the opening kickoff, fought through the injury to make a 23-yard field goal with 9 seconds left in a 23-20 victory over Oakland on Sunday.
Coach Andy Reid downplayed a report that said Akers could miss from three to six weeks.
"It's a little too early to determine that," Reid said.
McNabb played with a sore chest, strained lower abdomen and a shin contusion. He finished with 365 yards passing and two touchdowns while throwing a career-high 52 passes.
McNabb was tested last week for a sports hernia, a tear in the abdominal area that likely would need surgery. Though the possibility he has a sports hernia hasn't been completely ruled out, McNabb is willing to play through the pain.
"It would be great to not have any injuries and just go out and play football and have fun," he said Monday, talking about his various aches and pains. "But in life, there are adversities. It all depends on how you'll be able to overcome the adversities and move on."
Harrison's status was uncertain Monday after he injured his knee in a win at Pittsburgh the previous day. Coach Bill Belichick refused to disclose any information until he is required to file an injury report with the league on Wednesday.
But Harrison's teammates made it pretty clear the strong safety is done for the season with a knee injury.
"I went in at halftime and you could just tell that he was hurting," free safety Eugene Wilson said. "He had tears in his eyes because he loves the game so much and to go down and know that you might not be able to play, it hurts."
EXTRA TIME FOR PATRIOTS: A clock error added 52 seconds to the fourth quarter of the Patriots-Steelers game Sunday. The extra time aided the Patriots during a winning drive that ended with Adam Vinatieri's 43-yard field goal with 1 second remaining.
The Patriots won 23-20, their fourth victory against the Steelers in five games since 2001, including AFC championship game victories during the 2001 and 2004 seasons.
The NFL acknowledged the mistake Monday, with director of officiating Mike Pereira issuing a statement: "The on-field officiating crew, which oversees the official game clock operated in the press box, failed to recognize that the clock was improperly reset."
The mistake occurred after the second play of the fourth quarter, a reverse by Steelers wide receiver Cedrick Wilson for no gain on second-and-10 from the Pittsburgh 30 with the Steelers ahead 13-10.
There were 14 minutes, 51 seconds remaining when the play started and, by the time, a false start penalty was called on Steelers guard Kendall Simmons, the Heinz Field clock had run down to 13:59.
But before the next play started, the clock reverted back to 14:51 — the time left before the Wilson run.
HENRY SUSPENDED: The Tennessee Titans lost their insurance policy for oft-injured Chris Brown when the NFL suspended running back Travis Henry for four weeks Monday for violating the league's substance abuse policy. Coach Jeff Fisher said the Titans likely will make a roster move because the suspension leaves them with only Brown, rookie Damien Nash, a fifth-round draft pick out of Missouri deactivated for the first three games, and fullback Troy Fleming on the roster.
