After recent controversies surrounding NBA prop bets, several major sportsbooks have implemented restrictions on betting for players on two-way or 10-day contracts according to David Purdum of ESPN.

Notable operators, including FanDuel, DraftKings, BetMGM, and ESPN BET, will not offer under bets on these players as a precaution against potential manipulation attempts.

This decision comes in light of discussions held between the NBA and sportsbooks over the summer, focusing on safeguarding the integrity of the league's games.

The catalyst for this change was the scandal involving former Toronto Raptors forward Jontay Porter, who was banned from the league for his involvement in a gambling scheme centered on prop bets related to his performance statistics.

"We are pleased that these actions have been taken to help protect the integrity of our games," an NBA spokesperson stated. 

FanDuel emphasized its ongoing collaboration with partners to ensure that betting markets align with established standards, while DraftKings expressed gratitude for the opportunity to engage with the NBA on this pressing issue.

A spokesperson for BetMGM also confirmed the decision to avoid under betting on prop wagers for selected players, reinforcing the collective effort to uphold the integrity of NBA games.

At the time, Porter was on a two-way contract with the Raptors and had limited playing time in specific games, notably exiting a January 26 matchup against the Los Angeles Clippers and a March 20 game against the Sacramento Kings after only a few minutes on the court.

Porter later pleaded guilty to conspiracy to commit wire fraud on July 10 and is set to be sentenced on December 18 in New York.
