The Chicago Tribune earlier reported the news.
Urlacher was fined $15,750 for a horse-collar tackle on the Vikings' Adrian Peterson on Nov. 25, and he appealed that fine.
He also plans to appeal this one, according to the Trib, which quoted Urlacher as saying "My last appeal went real good."
It's been a tough week for Urlacher, who suffered a Grade 2 hamstring strain against the Seahawks. He could miss the rest of the regular season.
