Jontay Porter is under investigation by the NBA following multiple instances of betting irregularities over the past several months, sources told ESPN.

Prop bets involving Porter from games on Jan. 26 and March 20 are under investigation with the league "looking into it."

There was increased betting interest on the under for Porter props, which for the night were set at around 5.5 points, 4.5 rebounds and 1.5 assists. There was also an over/under for Porter's made 3-pointers, which was 0.5.

Porter played just four minutes before leaving the game because of what the Raptors said was an aggravation of an eye injury he had suffered four days earlier in a game against the Memphis Grizzlies. Porter did not score against the Clippers but three rebounds and one assist, and he did not attempt a 3, meaning the under hit on all of the props.

On March 20, in a game against the Sacramento Kings, Porter played just three minutes before leaving the game because of what the Raptors said was an illness and did not return. He did not score, attempted and missed one shot, and had two rebounds.

Sportsbooks had his over/unders set at around 7.5 points and 5.5 rebounds.

The next day, DraftKings SportsBooks reported to its users that Porter's prop bets were the No. 1 moneymaker from the night in the NBA.

"People were trying to do whatever they could to bet Jontay Porter props [against the Clippers]," the source said. "And then, just a few days ago, the same thing. We had a bunch of people trying to bet under for more."

Porter missed games on Saturday and Monday for personal reasons.
