Forbes has released its annual list of the world's 500 wealthiest people, and a number of prominent sports figures made the cut.

Stan Kroenke - owner or part-owner of the St. Louis Rams, Colorado Avalanche, Denver Nuggets, Colorado Rapids and Arsenal FC - is the wealthiest individual using sports as a primary source of income. Kroenke, 66, is worth $5.6 billion and is listed as the 253rd richest person in the world.

Kroenke isn't the richest owner in the NFL, however. The list distinguishes individuals who use sports as a main source of income from those involved in sports who have larger sources of income from non-sports interests. Microsoft co-founder Paul Allen, who owns the Seattle Seahawks and Portland Trail Blazers and partially owns the Seattle Sounders, is worth $15.9 billion and ranked No. 56 on the list. (Bill Gates, who co-founded Microsoft with Allen, ranks No. 1 overall on the list with $76 billion.)

Tampa Bay Buccaneers and Manchester United owner Malcolm Glazer and his family are ranked No. 354 with $4.2 billion, and Dallas Cowboys owner Jerry Jones ranks No. 551 with $3 billion.

Another prominent sports figure on Forbes' list is Phil Knight, who founded Nike and serves as the company's CEO. Knight is worth $18.4 billion, according to Forbes. The list names him the 42nd-richest person in the world.
