A lawyer for Jontay Porter says the former Toronto Raptors forward who was given a lifetime ban by the NBA because of a sports betting scandal was “in over his head” with a gambling addiction.

The statement comes after a fourth man was arrested Friday in the scandal. Ammar Awawdeh turned himself following the arrests of three co-defendants earlier this week.

A court complaint accuses him of pressing an NBA athlete to resolve gambling debts by claiming health problems and leaving games early. The tactic would guarantee a payout for anyone who bet on him to underperform. Awawdeh’s lawyer declined to comment.
