In Major League Baseball (MLB), the injured list (IL) is a method for teams to remove their injured players from the roster in order to summon healthy players. Before the 2019 season, it was known as the disabled list (DL).
Athletics has been contested at every Summer Olympics since the birth of the modern Olympic movement at the 1896 Summer Olympics. The athletics program traces its earliest roots to events used in the ancient Greek Olympics. The modern program includes track and field events, road running events, and race walking events. Cross country running was also on the program in earlier editions but it was dropped after the 1924 Summer Olympics.
A Major League Baseball roster is a list of players who are allowed, by league agreement, to play for a Major League Baseball (MLB) team. Each MLB team maintains two rosters: an active roster of players eligible to participate in an MLB game, and an expanded roster encompassing the active roster plus additional reserve players.
Major League Baseball transactions are changes made to the roster of a major league team during or after the season. They may include waiving, releasing, and trading players, as well as assigning players to minor league teams.
The injured reserve list is a designation used in North American professional sports leagues for athletes who suffer injuries and become unable to play. The exact name of the list varies by league; it is known as "injured reserve" in the National Football League (NFL) and National Hockey League (NHL), the "injured list" in the Canadian Football League (CFL), and the injured list in Major League Baseball (MLB). The National Basketball Association (NBA) does not have a direct analog to an injured reserve list, instead using a more general-purpose "inactive list" that does not require a player to be injured.
The Mexico national baseball team is the baseball team that represents Mexico in international tournaments. It is currently the 3rd-ranked baseball team in the world.
Designated for assignment (DFA) is a contractual term used in Major League Baseball (MLB). A player who is designated for assignment is immediately removed from the team's 40-man roster, after which the team must, within seven days, return the player to the 40-man roster, place the player on waivers, trade the player, release the player, or "send outright" the player from the 40-man roster into Minor League Baseball.

The 1960 NFL expansion draft was the first National Football League (NFL) draft in which a new expansion team, which eventually became known as the Dallas Cowboys, selected its initial players. The NFL awarded Dallas, Texas a franchise to compete for revenue with Lamar Hunt's Dallas Texans of the upstart American Football League. However, the Dallas expansion franchise was approved too late for it to participate in the 1960 NFL draft which had been held on November 30, 1959. Thus, Dallas is the only NFL expansion team to not have had the benefit of a college draft in its first year.
