From Chris Mortensen of ESPN.com:

New England Patriots offensive tackle Matt Light and Miami Dolphins linebacker Channing Crowder have both been fined $15,000 by the NFL, but not suspended, for their roles in an on-field altercation during the Patriots' win at Miami on Sunday.

Both men were fined the same amount for their verbal and physical confrontation, for which they were ejected midway through the fourth quarter.

According to league sources, both players were interviewed by league office, as well as the game officials. It was determined that Crowder verbally instigated the confrontation, but both men were assessed equal fines for the fracas.

The fight occurred after Light blocked Crowder, whose helmet fell off, on Stephen Gostkowski's 30-yard field goal midway through the fourth quarter.

Miami's Matt Roth knocked down New England's Russ Hochstein, forcing Light backward and into Gostkowski. Light got up and he and Crowder pushed each other in the face. Light then grabbed Crowder's dreadlocks in his left hand and hit him three times on the head with his right.

Crowder broke free and ran away with a huge grin. Both received personal foul penalties and were ejected. As they walked off, Light smiled and Crowder raised his hands to elicit cheers from his hometown fans.
