3.1 Fouls
An attempt to unfairly disadvantage an opponent through physical contact is illegal and is called a foul. These are most commonly committed by defensive players; however, they can be committed by offensive players as well. Players who are fouled either receive the ball to pass inbounds again, or receive one or more free throws if they are fouled in the act of shooting, depending on whether the shot was successful. One point is awarded for making a free throw, which is attempted from a line 15 feet (4.6 m) from the basket.
The referee may use discretion in calling fouls (for example, by considering whether an unfair advantage was gained), sometimes making fouls controversial calls or no-calls. The calling of fouls can vary between games, leagues and even among referees.
A player or coach who shows poor sportsmanship, such as by arguing with a referee or by fighting with another player, can be charged with a more serious foul called a technical foul. The penalty involves free throws (where, unlike a personal foul, the other team can choose any player to shoot) and varies among leagues. Repeated incidents can result in disqualification. Blatant fouls with excessive contact or that are not an attempt to play the ball are called intentional fouls (or flagrant fouls in the NBA). In FIBA, a foul resulting in ejection is called a disqualifying foul, while in leagues other than the NBA, such a foul is referred to as flagrant.
If a team exceeds a certain limit of team fouls in a given period (quarter or half) – four for NBA and international games – the opposing team is awarded one or two free throws on all subsequent non-shooting fouls for that period, the number depending on the league. In the US college and high school games, if a team reaches 7 fouls in a half, the opposing team is awarded one free throw, along with a second shot if the first is made. This is called shooting "one-and-one". If a team exceeds 10 fouls in the half, the opposing team is awarded two free throws on all subsequent fouls for the half.
When a team shoots foul shots, the opponents may not interfere with the shooter, nor may they try to regain possession until the last or potentially last free throw is in the air.
After a team has committed a specified number of fouls, it is said to be "in the penalty". On scoreboards, this is usually signified with an indicator light reading "Bonus" or "Penalty" with an illuminated directional arrow indicating that team is to receive free throws when fouled by the opposing team. (Some scoreboards also indicate the number of fouls committed.)
If a team misses the first shot of a two-shot situation, the opposing team must wait for the completion of the second shot before attempting to reclaim possession of the ball and continuing play.
If a player is fouled while attempting a shot and the shot is unsuccessful, the player is awarded a number of free throws equal to the value of the attempted shot. A player fouled while attempting a regular two-point shot, then, receives two shots. A player fouled while attempting a three-point shot, on the other hand, receives three shots.
If a player is fouled while attempting a shot and the shot is successful, typically the player will be awarded one additional free throw for one point. In combination with a regular shot, this is called a "three-point play" or "four-point play" (or more colloquially, an "and one") because of the basket made at the time of the foul (2 or 3 points) and the additional free throw (1 point).
3.2 Injuries
Ankle Sprains
Treatment for an ankle sprain involves rest, ice, compression, and elevation (RICE). The need for X-rays and evaluation by a physician is determined on a caseby- case basis and depends on the severity and location of pain. Pain and swelling over the bone itself may need further evaluation. An injury to the ankle in a child who is still growing could represent a simple sprain or could be the result of an injury to the growth plates located around the ankle and should be evaluated by a physician.
Jammed Fingers
Jammed fingers occur when the ball contacts the end of the finger and causes significant swelling of a single joint. Application of ice and buddy taping the finger to the adjacent finger may provide some relief and allow the athlete to return to play. If pain and swelling persist, evaluation by a physician or athletic trainer is recommended and an x-ray of the finger may be needed.
Knee Injuries
Basketball requires extensive stop and go and cutting maneuvers which can put the ligaments and menisci of the knee at risk. Injury to the medial collateral ligament is most common following a blow to the outside of the knee and can be often be treated with ice, bracing and a gradual return to activity.
An injury to the anterior cruciate ligament is a more serious injury and can occur with an abrupt change in direction and landing for the jump. Although this ligament tear is most commonly a seasonending injury that requires corrective surgery, current techniques used to repair the ACL ligament generally allow the player to return to play the following season.
Deep Thigh Bruising
Treatment includes rest, ice, compression, and elevation. Commercially available girdles with thigh pads are now available for protection.
Facial Cuts
Depending on the depth of the injury, the cut may require stitches or a "butterfly" sterile tape. Ice may provide pain relief and decrease swelling. Players can return to play after all blood is removed and the wound is dressed.
Stress Fractures
Stress fractures can occur from a rapid increase in activity level or training or from overtraining. Stress fractures in basketball most commonly occur in the foot and lower leg (tibia). Once diagnosed, a period of immobilization and non-weight bearing is recommended. Return to play is permitted once the fracture has completely healed and the athlete is pain free.
