Disabled list

If a major league player cannot play due to a medical condition, he may be placed on the 15-day disabled list. The team then frees up a spot on their active major league roster, and the player may not play for at least 15 consecutive days. An injured player may also be placed on the 60-day disabled list. The team then frees up a spot on both the active major-league roster and the 40-man roster; the player may not play for at least 60 consecutive days. Players on either disabled list may remain on the list for as long as required to recover.
