The term wild card refers broadly to a tournament or playoff berth awarded to an individual or team that has not qualified through normal play.

In international sports, the term is perhaps best known in reference to big international sporting events such as The Olympic Games or Wimbledon. Countries which fail to produce athletes able to meet performance requirements to compete are granted "wild cards", which enable them to send competitors to tournaments even if those competitors' abilities are below the required standards. In some instances, wild cards are given to the host nation in order to boost their chances. However, in Olympic and World Championship competitions in track and field and swimming, nations are automatically allowed to enter two competitors. Thus these are not to be considered wild cards which are always granted by the tournament organizers. In some other sports in Olympics, such as judo, archery and badminton, wild card practice is in use, and they are granted by the respective sport federations. On rare occasions, a competitor who gained entry by wild card succeeds in winning a medal; Kye Sun-Hui won gold in judo at the 1996 Summer Olympics, and Goran Ivanišević won the 2001 Wimbledon Championships.

Sheen's personal life has also made headlines, including reports about alcohol and drug abuse and marital problems as well as allegations of domestic violence. He was fired from his role on Two and a Half Men by CBS and Warner Bros. on March 7, 2011. Sheen subsequently announced a nationwide tour.

Colin Rand Kaepernick (born November 3, 1987) is an American football quarterback for the San Francisco 49ers of the National Football League. He was drafted in the 2nd round, 36th overall pick in the 2011 NFL Draft. He played college football at Nevada.

Kaepernick was born in Milwaukee, Wisconsin. An adopted child of Rick and Teresa Kaepernick, Kaepernick is of mixed European and African descent and the youngest of their three children. He lived in Fond du Lac, Wisconsin until age four and attended grade school in Turlock, California.

Kaepernick graduated from the University of Nevada Reno in December 2010 with a bachelors degree in business management and is a member of Kappa Alpha Psi fraternity. He is known to have high character and a relatively unassuming personality off the field, as evidenced by an incident that took place during the summer of 2010 interning at a University of Nevada-themed sports apparel shop in Reno. One woman came in and, completely unaware she was speaking to Kaepernick, asked him to find his jersey. A manager at the store would later recall, "Colin said, ‘I’m pretty sure it’s No. 10, and it’s right over here.’ He rang up her purchase and everything."

Brown finished seventh in school history with 2,707 rushing yards and fifth with 28 rushing touchdowns. He twice earned second-team Associated Press All-Southeastern Conference honors, in 2002 and 2004.

Brown was drafted second overall by the Miami Dolphins in the 2005 NFL Draft. Brown started at running back for the Dolphins for the first four weeks of the season while Ricky Williams served a suspension, and shared carries with him when he returned in week five. Brown became the feature back in 2006 due to Williams' full year suspension. Brown sat out three games due to a broken hand suffered on Thanksgiving Day in a game against the Detroit Lions, returning in week 16. He played in the first seven games of the 2007 season before suffering a knee injury which knocked him out for the remainder of the season. Williams started over Brown in the first two games of the 2008 season, but shared carries with him after week two. Brown had 916 yards and ten touchdowns in 2008, which led to his first Pro Bowl selection following the season. He was placed on injured reserve for the second straight season after suffering a foot injury in week nine of the 2009 season. Brown rushed for 734 yards and five touchdowns in 2010, as he started in all 16 games. He played for the Philadelphia Eagles in 2011 following a six-year career with the Dolphins.
