Three Tennessee sports betting operators received fines from the state’s betting regulator earlier this week.

BetMGM received the largest fine of the operators, accepting a $25,000 financial hit for allowing bettors to wager on penalties. The state prohibits wagering on topics like injuries and penalties.

Action 24/7, which only operates in Tennessee, received an $18,000 fine from the Tennessee Sports Wagering Council. Action 24/7 was fined for allowing self-excluded bettors to deposit and place bets using the betting app.

Allowing self-excluded bettors to wager often draws the ire of state regulators, who try to emphasize responsible gambling best practices.

Penn Interactive (ESPN BET) received $12,000 worth of fines this week for an issue similar to Action 24/7’s. The operator received a $9,000 fine for failing to self-exclude one bettor, and it also accepted a $3,000 fine for pushing marketing materials to bettors on the state’s self-excluded list.
