UPDATED 12/6/18, 11:48 a.m. ET: Tristan Thompson’s lewd hand gesture during a Cavaliers-Nets game is going to cost him.

The league announced on Thursday that Thompson’s punishment for flipping off courtside hecklers would be $15k, TMZ reports, which is considerably less than the $25k fines Kevin Durant and Patrick Beverley were given for their respective fan incidents.

See original story below.

The father of Khloé Kardashian's child also plays basketball, and on Monday night Tristan Thompson was feeling pretty good about himself, despite wearing the jersey of a team half a game from the bottom of the crappier conference. That's because the Cavs captured their fifth win of the season, 99-97 over the Nets in Brooklyn.

To celebrate the win, Thompson decided to flip the bird to a few court-side fans:

You can hear some fans scream "Get out of here, you bum," but also: "Someone's gotta get that on video!" Someone did and promptly sent it to TMZ. Capitalism! Brief aside: What type of person talks smack to a player and when that player responds, hopes the offending hand gesture was caught on video? The game was in Brooklyn.

Like Patrick Beverley throwing the basketball at a Mavs fan who allegedly referenced the point guard's mother while cursing him out, and Kevin Durant's costly (25 stacks) curse at another Mavs fan when the Warriors were in town, it's likely the NBA docks Thompson some money for this. We hope it was worth the effort, but we're glad it happened somewhere that wasn't Dallas. 

TT has been playing inspired basketball of late, posting his seventh double-double over his last eight games. Even with his inspired play of late, the Cavs are not the team to beat in the East this season, and likely won't be until another LeBron is born in the state of Ohio some time in the year 2145.
