Former NFL Minnesota Vikings minority owner Reginald Fowler should be sentenced to seven years in prison and forfeited more than $740 million after pleading guilty to helping crypto exchanges evade money laundering rules, U.S. prosecutors said.

Prosecutors allege that Reginald Fowler founded Global Trading Solutions LLC, and that Fowler, through his company Crypto Capital, engaged in "shadow banking" for cryptocurrency exchanges, allowing them to exchange their digital currencies for cash. Reginald Fowler is accused of opening multiple accounts at Bank of America, falsely claiming that these accounts were used for real estate investment transactions, when the real purpose was to process cryptocurrency transactions.

Reginald Fowler will be sentenced by U.S. District Judge Andrew L. Carter Jr. on April 20 in Manhattan.
