MIAMI BEACH, Fla. — Authorities say two professional athletes have been arrested after fighting outside a Miami Beach nightclub.

Miami Beach Police Detective Vivian Thayer says St. Louis Rams linebacker Jo-Lonn Dunbar and NBA free agent Donte Green were arrested early Sunday outside Dream Nightclub in South Beach.

Thayer says the athletes got into a fight with each other outside the club.

Dunbar played for the New Orleans Saints from 2008 to 2011 and was on the team that helped New Orleans win Super Bowl XLIV.

In St. Louis this year, Dunbar is expected to be playing for defensive coordinator Gregg Williams, who coached Dunbar in New Orleans, and was a key figure in the bounty scandal that broke prior to the 2012 season.

Additional details about the altercation were not immediately available. Thayer says no other arrests were made.

Thayer says Dunbar and Green each face charges of battery and disorderly conduct.

Miami-Dade County jail records did not show either man in custody Sunday afternoon. Details about the bonds they posted were not immediately available.
