The NBA has directed its sportsbook partners to prohibit or restrict certain types of bets, according to David Purdum and Shams Charania of ESPN. The league sent a memo to its authorized gaming operators, including DraftKings and FanDuel, telling them to make a set of adjustments this season. ESPN's summary says the prohibited bets include a player prop parlay that was used in recent scandals.

Yahoo Sports described the move as an agreement between the league and the books, and its headline says the ban covers parlays involving the under on the same player's stats. That is the most specific description of the banned bet in the material we have. ESPN's account is framed as an instruction from the league, not a deal. The Associated Press, via Sportsnet, says only that certain bets are being banned, "including some player props." Hoops Rumors, citing ESPN, says the memo lists the adjustments bettors will see, but its feed excerpt cuts off before naming them.

That leaves gaps. We don't have the full list of banned or restricted bets, the memo's effective date, or how the league will enforce it. The sources we have don't say which sportsbooks have responded beyond the two named operators. The AP's wording that "some" player props are affected suggests the ban is narrower than a blanket prohibition on props, but the reporting we have doesn't spell out its limits.

Yahoo ties the news to multiple betting scandals that have threatened the league's integrity in recent years. Hoops Rumors also describes the memo as a response to recent scandals. None of the reporting we have names the specific cases, players or games, and we haven't tried to fill that in here.

What to watch next is the full text of the memo and how the operators implement it in their NBA markets this season. Whether the league's list grows beyond the parlay type ESPN singled out is not addressed in the reporting.
