when the player can resume full playing activities. If the injury turns out to be minor, then the player may resume playing immediately without having to serve the minimum term on the injured list. This also allows a valuable, slightly injured player to continue to contribute in a limited role, such as pinch hitting. However, depending upon the circumstances, the team may find itself effectively shorthanded in the meantime. Retroactive placement on the IL may be made at most 10 days after the last time the affected player played in a game. This allows a club to defer the decision to place a player on the injured list until more information can be learned about the extent and impact of the injury. Starting with the 2011 season, Major League Baseball instituted a new, shorter injured list: a 7-day injured list specifically for concussions. The idea is to prevent long-term brain damage which may take up to 7 days by current standards, without having to serve the 10-day minimum on the regular IL. If a player is not activated from the concussion injured list after 10 days, he is automatically transferred to the 10-day injured list. Players recovering from an injury may appear in a limited number of minor league games while still on the injured list in order to prepare for reactivation. Pitchers may play on a minor league club for up to 30 days; others for up to 20 days. Paternity list Also in 2011, Major League Baseball instituted a paternity list. This allows a team to replace a player who is an expectant father for 1–3 days on the roster to be available for the birth of his child. Bereavement list A player may be placed on the bereavement list upon attending to a seriously ill member in the player's immediate family or to a death in the family. The bereavement list may span from a minimum of three to a maximum of seven games. Umpiring's bereavement list for death in the immediate family may span up to a full season. Minor League Baseball Minor League Baseball uses both a 7-day injured list, with players on this list counting toward a parent major league club's reserve list limit, and a 60-day injured list, players on which do not count against a major league team's reserve list limit. Players who are on the 40-man roster but become injured while
