A well-attended voluntary mini-camp in Las Vegas last week did not come without a cost for the Minnesota Timberwolves.

NBA front-office sources told ESPN.com on Tuesday that the Wolves were fined $200,000 for the two-day excursion, which was suggested by new coach Dwane Casey as a means for the members of a revamped roster to begin learning Casey's system and start building camaraderie.

The league, which did not announce the fine, prohibits teams from conducting organized team practices or functions in the offseason.

The Wolves, through team spokesman Mike Cristaldi, declined comment Tuesday night.

Casey hatched the idea as part of the Wolves' attempts to gain some distance from last season's chemistry nightmare. Coming off a trip to the Western Conference finals in 2004 -- the first time in franchise history it advanced past the first round of the playoffs -- Minnesota swooned all the way into the lottery in 2004-05, costing coach Flip Saunders his job at midseason and leading to the summertime ouster of guards Sam Cassell and Latrell Sprewell.
