Detroit center Dominic Raiola says that he isn't sorry for making an obscene gesture toward Lions' fans because their heckling went too far. Raiola said fans have been hard on him because he's been with the team since 2001. "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."
