Kroenke adds St. Louis Rams to collection

The NFL did not disclose financial terms of the deal.

Kroenke, whose fortune Forbes magazine has estimated at $2.7 billion, also owns the NBA's Denver Nuggets, the NHL's Colorado Avalanche, Major League Soccer's Colorado Rapids and National Lacrosse League team Colorado Mammoth.

"Stan has been a familiar and respected figure in the National Football League for more than 15 years," said NFL Commissioner Roger Goodell. "He is a proven businessman and has experienced success in all of his sports franchises, as well as serving as a responsible community leader."

Prior to the Rams, the St. Louis Cardinals were the city's NFL team from 1960 to 1987 before they moved to Phoenix and later became the Arizona Cardinals.
