John Lynch will be out for two to four weeks after having a fractured tailbone diagnosed, the Broncos announced yesterday.

Denver's veteran safety went down after being hit in the side by Falcons wide receiver Brian Finneran in Sunday's 41-28 loss. After trainers helped him up, Lynch walked toward the Atlanta huddle and started yelling at the Falcons.

He wasn't available after the game, but several Broncos said Lynch felt Finneran's block was a cheap shot.

Denver Coach Mike Shanahan said the block appeared legal, "but it was one of those blindside shots that kind of catches you off guard."

Nick Ferguson will start in place of Lynch in next Sunday's game against Houston. The Broncos have a bye after that, then play at New Orleans.

Vikings Might Rest Moss

Minnesota's Randy Moss might miss his first career game because of a lingering right hamstring strain that hasn't gotten worse -- but isn't getting a whole lot better.

The Vikings will decide later this week whether or not they should rest Moss on Monday night at Indianapolis.

Since being hurt before halftime of Minnesota's game at New Orleans on Oct. 17, Moss has been limited to just 11 snaps over the last 10 quarters. Though he leads the team with eight touchdown catches and his consecutive games streak remains alive at 103, he has gone the last two games without a reception.

"Can we get him back at full speed sooner if we just sit him?" Coach Mike Tice said. "Or is he going to be back at full speed the same length of time if we just play him in a limited role -- based on the fact that in two weeks he didn't take a step back?

"So have to monitor that, as the week goes on. We have to do what's best for the team to achieve our goals, which are to win the division and win the world championship. We can't do what's best for a streak, or anything of that nature."

Lions' Porcher Retires

Robert Porcher retired, ending a 13-season career with the Detroit Lions, for whom he is the career leader in sacks.

"I've thought about this day for a lot of the last three years," Porcher said. "We all think we can play forever, and I was no different, but now the time has come to step aside."

Porcher, who retired with 951/2 career sacks, already had announced this would be his last season, but he ended his career early after being inactive for Detroit's first seven games. . . .

San Francisco 49ers defensive end Brandon Whiting will miss the rest of the season with a torn ligament in his left knee suffered during Sunday's loss to Chicago.

Wide receiver Randy Moss, who has eight touchdown catches, might sit out the Vikings' next game to allow his strained hamstring to fully heal.
