Jimmy Butler is back with the Minnesota Timberwolves, and his first practice of the season had fireworks.

Butler, who asked for a trade more than three weeks ago, practiced with the Timberwolves for the first time this season in Minneapolis on Wednesday. ESPN reported that Butler verbally challenged players, coaches and even general manager Scott Layden in the practice, during which Butler dominated the team’s scrimmages even when going up against stars like Karl-Anthony Towns and Andrew Wiggins.

The four-time NBA All-Star said he warned coach Tom Thibodeau before practice that he would let his emotions out if he played, and that’s apparently what happened.

Butler told ESPN that he plans to be back at practice Thursday, but cautioned that the relationship with the Timberwolves is still fractured.
