If a player's momentum carries him or her off the court, he or she can be the first player to touch the ball after returning inbounds. That player must not have left the court voluntarily and must immediately return inbounds. That player must have something in and nothing out. It is not necessary to have both feet back inbounds. It is a violation for a player to intentionally leave the court for an unauthorized reason.
A player inbounding the ball may step on, but not over the line. During a designated spot throwin, the player inbounding the ball must keep one foot on or over the three-foot wide designated spot. An inbounding player is allowed to jump or move one or both feet. A player inbounding the ball may move backward as far as the five-second time limit or space allows. If player moves outside the three-foot wide designated spot it is a throwin violation, not traveling. In gymnasiums with limited space outside the sidelines and endlines, a defensive player may be asked to step back no more than three feet. A player inbounding the ball may “dribble” the ball on the out-of-bounds area prior to making a throwin.
