KANSAS CITY, Mo. - Carl Peterson has resigned as president and general manager of the Kansas City Chiefs, effective at the end of the season, owner Clark Hunt announced yesterday.

Peterson, the director of player personnel when the Eagles reached the Super Bowl after the 1980 season, took over in Kansas City in 1989.

He hired Marty Schottenheimer as coach and they built the Chiefs into an NFL powerhouse over the next 10 years. From 1990 to '99, Kansas City went 102-58 (.638), making the Chiefs one of seven teams in NFL history to win 100 games in a decade.

However, Kansas City has faltered in the last decade and hit a low point Sunday in an emotionally draining 22-21 loss to San Diego, which left the Chiefs 2-12.

The Chiefs are 176-141-1 under Peterson; they made the playoffs 13 times in his first 18 seasons. But the franchise never reached the Super Bowl under his guidance, and has not won a playoff game since reaching the AFC championship game in 1993.

Titans. Coach Jeff Fisher said that defensive tackle Albert Haynesworth and defensive end Kyle Vanden Bosch would miss the final two games of the regular season but that both Pro Bowlers would be back for the playoffs.

Haynesworth sprained a ligament in his left knee Sunday. Vanden Bosch injured his groin Dec. 7.

"I look at this as good news," Fisher said. "We'll have them both back."

Vikings. Defensive tackle Pat Williams will be sidelined from two to six weeks with a fractured shoulder. He was hurt Sunday in a win against Arizona.

Fred Evans will take his place.

Bills. Coach Dick Jauron said he anticipates returning next season, although there has been no public assurance from team management or owner Ralph Wilson.

Buffalo is 6-8 after Sunday's loss to the Jets.

The Bills announced that rookie wide receiver James Hardy will miss the rest of the season after suffering a torn ligament in his left knee.

Chargers. Wide receiver Malcom Floyd was hospitalized overnight in Kansas City after suffering a collapsed lung in Sunday's victory against the Chiefs. Floyd was flying to San Diego yesterday, coach Norv Turner said.

Giants. Corey Webster, who has developed into one of the NFL's top cornerbacks over the last year, signed a five-year, $43 million contract extension. Webster will receive $20 million in guaranteed money under the deal that runs through 2013.

The fourth-year player would have been a free agent at the end of the season.

Jaguars. Starting middle linebacker Daryl Smith injured his groin against Green Bay on Sunday and will not play Thursday night against Indianapolis.

Rams. Wide receiver Derek Stanley will need reconstructive surgery on his left knee for an injury he suffered in Sunday's loss to the Seahawks, coach Jim Haslett said.

Buccaneers. Monte Kiffin, Tampa Bay's longtime defensive coordinator, said he plans to leave the Bucs at the end of the season - his 13th with the team - to join his son Lane's staff at Tennessee.

Steelers. NFL owners may vote tomorrow on whether to accept the restructured ownership plan in which Pittsburgh chairman Dan Rooney and his son will buy most of the shares owned by other family members.

The finance committee, chaired by Tom Benson of the New Orleans Saints, reviewed the matter yesterday. At least 24 of the 32 franchises need to vote in favor of the restructuring.

League rules stipulate that the principal owner control at least 30 percent of the club. Previously, Dan Rooney owned the same 16 percent stake as his brothers.

Cowboys. When the 20-8 victory over the New York Giants was over Sunday night, Terrell Owens, Tony Romo and Jason Witten were standing together and smiling.

"Sometimes people think that stuff that gets talked about decides football games," Romo said. "What decides it is the execution of the players on the field and the preparation you put in."

The Cowboys survived a week of public scrutiny to beat the Giants and stay in the NFC wild-card race.

They had spent more time during the week answering questions about their own squabbles than about playing New York - including talk of T.O.'s being upset about Romo's friendship with Witten.

The Cowboys sacked Eli Manning eight times, three by DeMarcus Ware, who now has 19 this season, 31/2 shy of the NFL record held by a former Giant, Michael Strahan.
