LAS VEGAS—Head athletic trainer Casey Smith left his seat in the stands and headed toward the Dallas Mavericks’ bench in the first half of Dallas’ game against the Brooklyn Nets. There, he took a seat next to Isaiah Roby, the rookie Dallas selected in the second round of June’s NBA Draft. Of concern for both was Roby’s left hand.
At some point during the action, Roby hurt a finger on his hand. After a few minutes of attention, he checked back into the game with his ring and middle fingers taped together.
