The NFL said the officiating crew at the Packers-Vikings game Sunday night made a mistake by not blowing the whistle when Vikings WR Chris Walsh took a knee in the closing seconds.

Antuan Edwards's hard hit on Walsh sparked a melee in front of the Vikings' bench after Darren Sharper's interception and 66-yard return on the next play sealed the Packers' 26-22 victory.

The league is reviewing the fight and will announce any fines Wednesday or Thursday, spokesman Greg Aiello said.

Jim Daopoulos, the league's supervisor of officials, said the whistle should have been blown the moment Walsh took a knee.

"Yes, we missed that one," he said.

* FIGHTING WORDS: Rams Coach Mike Martz did not back down from Sunday's postgame comments, when he indicated that he could not count on some of his players.

Martz said that too many players became demoralized by Dante Hall's two kick returns, plus a fumble return for a touchdown, in the first half of Sunday's 49-10 loss to the Chiefs. He said past teams have been mentally tougher and more able to overcome mistakes.

"At the end of the game, I felt like defensively we had a tremendous letdown," Martz said.

St. Louis (5-8) is out of playoff contention. Also, the Rams said that Marshall Faulk's playing time might be limited for the rest of the season because of a high right ankle sprain.

* MOVES: 49ers punt returner Jimmy Williams will miss the rest of the season with torn ligaments in his left knee. Williams leads the NFC with 16.8 yards-per-return average. . . .

Panthers LB Dan Morgan needs surgery to repair his dislocated left shoulder and may miss the final three games of the season.
