How do I claim a player off waivers?
STANDARD LEAGUE WAIVERS
All players not on a fantasy roster will be placed on waivers. They will be individually locked at the start of their team's first game of the day. Their status will change from "FA" to Claim.

Players dropped by an owner reside on waivers for at least 24 hours before clearing waivers. At the clearance time, the player is assigned to either a team (if a claim was made) or the free-agent pool (if no claim was made). Unclaimed players not acquired during the waiver period become free agents and may be picked up on a first-come, first-serve basis without affecting a team's waiver position.

If multiple claims are submitted for a particular player, the claim is resolved based on the waiver position of each involved team. A team's waiver position is the relative power you have when selecting a player off of the waiver wire. When more than one team requests a player in waivers, the player is awarded to the team with the better waiver position (closest to "1"). When a claim is resolved, the waiver position for the team that receives the player is changed to the lowest possible priority (10, for example in a 10 team league), and all the other teams move up a position.

WAIVER SYSTEM (In-season)
Standard leagues use the following method for determining which team has priority in waiver claims.

    Move to last after claim, never reset order - The team which makes the most recent pickup is automatically moved to the last slot.
    Waiver claims can be made at any time before the player clears waivers. Any player who is dropped within 24 hours of a game start is not available to be added to a team roster, and will appear on waivers 8 hours after being placed on waivers.
    Waivers process daily beginning at 3 a.m. ET.
