Detroit center Dominic Raiola says he has no remorse for making an obscene gesture toward Lions fans because their heckling went too far.
"I don't take one thing back," he said yesterday.
NFL spokesman Randall Liu said the league will look into it.
Raiola said fans have been particularly hard on him because he has been with the team since 2001, when it started a slide that has become the NFL's worst eight-season stretch in more than a half-century.
Raiola extended his middle finger toward fans during the winless Lions' 20-16 loss to Minnesota on Sunday.
"I'm just tired of hearing it coming at just me," Raiola said. "It's coming at me because I've been here for years. I've been through the losing. Me, Jeff [Backus] and whoever else are the head of the losing."
The Lions (0-13) have lost 20 of their last 21 and are 31-94 since 2001, falling to the league's poorest winning percentage (.248) over an eight-season stretch since 1950.
"I'm just so frustrated," Raiola said. "I'm tired of being a doormat for people to just talk to us how they want to talk to us. I'm just not going to put up with that anymore."
Raiola wishes he could give some fans his home address.
"I'd do that, but you can't," he said. "Nobody plays with fists. Everybody wants to play with metal."
The NFL has fined players for making similar gestures this season and in past years such as 2006 when Atlanta quarterback Michael Vick extended both middle fingers toward fans at a home game.
* Detroit quarterback Daunte Culpepper had an MRI on his passing shoulder, leading to doubt he will play Sunday at the Indianapolis Colts.
* Washington left tackle Chris Samuels is out for the season with a torn right triceps. He suffered the injury in Sunday night's loss to Baltimore.
* Green Bay veteran right tackle Mark Tauscher will miss the Packers' last three games of the season due to a torn ACL in his left knee suffered Sunday against Houston.
* Kicker Morten Andersen, the NFL's career-leading scorer, is retiring because of knee problems. The 48-year-old Dane, who scored 2,544 points during his 25-year career, played for the Atlanta Falcons the past two seasons but wasn't able to get a contract this year.
* Denver rookie tailback Peyton Hillis has a torn right hamstring and is done for the season. He suffered the injury Sunday against Kansas City.
* Cincinnati quarterback Carson Palmer will throw for longer distances this week, an encouraging development as he tests his injured passing elbow. Palmer hasn't played since Oct. 5 because a tendon and ligament in his right elbow are partially torn from the bone.
* Minnesotga coach Brad Childress said quarterback Gus Frerotte is "very sore" after hurting his lower back in the win over Detroit Sunday. Frerotte left Ford Field on a cart after getting hurt late in the second quarter.
Tarvaris Jackson got his old job back for the second half, but Childress says Frerotte is still the starter if he's healthy.
* San Francisco running back Frank Gore injured an ankle in the second half against the Jets Sunday and might not play against Miami this weekend.
* Fox televised a clip of Minnesota owner Zygi Wilf's postgame locker-room speech after Sunday's victory at Detroit, and tight end Visanthe Shiancoe was inadvertently shown naked in the background. He was wearing a towel that did little to cover him.
