Dolphins' running back Ronnie Brown has been fined for his end zone celebration against the Chargers last Sunday. After scoring on a 5-yard run out of the Wildcat formation, Brown and two of his offensive linemen gathered in the end zone and performed a line dance. The performance, which Brown admitted he and the line practiced during last Friday's walkthrough, violated the league's rules against group celebrations. "We were enjoying ourselves, having fun," said Brown.
