NHL Waivers and the Waiver Wire Explained

The NHL waiver wire is one of the league's quietest mechanisms and one of its most consequential. Every time a team needs to send a veteran to the AHL, every time they want to free up cap space, every time training camp ends and the 23-man roster gets finalized — somebody goes on waivers, and twenty-nine other teams get a look at them.

This guide walks through who has to clear waivers, who's exempt, what happens during the 24-hour claim window, and how teams actually use the wire as a tactical tool.

What waivers are

When an NHL team wants to send a player who is not waiver-exempt down to the AHL, they can't just do it. They have to first put the player on waivers, which makes him available to every other NHL team. The rule exists to prevent richer teams from stockpiling NHL-quality talent in the minor leagues by giving struggling teams a chance to claim depth players for free.

Practical mechanics:

• The team submits the player to waivers by 2 p.m. Eastern.
• Every other NHL team has until 2 p.m. Eastern the next day to file a claim.
• If multiple teams claim him, the team with the worst current points percentage wins — reverse standings order.
• If no one claims him, he clears waivers and the team can send him to the AHL.

The claiming team picks up the full contract — same term, same cap hit, same salary structure — for nothing in return. No assets exchanged, no draft picks. Just absorb the contract.

Who has to clear waivers (and who doesn't)

Waiver exemption is determined by two factors: age at first pro contract and total NHL/AHL games played. The CBA lays out a detailed table, but the practical summary is:

• Most ELC players are exempt for at least the first year, often longer.
• Once a player crosses the games-played threshold for his position (different for forwards, defensemen, and goalies), he loses exemption.
• Players signed at older ages have shorter exemption windows; players signed at 18 have longer ones.

The thresholds for losing exemption (approximate, based on the standard CBA framework):

Position	Approximate games-played ceiling
Skaters signed at 18	~160 NHL games or 5 pro seasons
Skaters signed at 19	~80 games or 4 pro seasons
Skaters signed at 20	~70 games or 3 pro seasons
Skaters signed at 21–22	~60 games or 2 pro seasons
Goalies	Lower thresholds at every age

(Exact numbers shift by position; goalies have their own slower set, and the CBA recalculates with each game played at the AHL or NHL level.)

For the team, the practical question every fall is: who do we have to clear waivers to send down? That answer drives roster construction in training camp.

What happens when a player gets claimed

When a player is claimed off waivers, two things happen at once:

1. The claiming team gets the player and his contract. Same AAV, same term, no trade required. The player reports to the claiming team and is on their roster effective immediately.
2. The releasing team loses the player and the cap hit. No assets in return, but the cap space is freed.

Claims used to happen relatively often — a few times a week in October. They've become rarer in the cap era because most NHL teams are cap-constrained and don't have room to absorb another contract on a whim. When claims do happen, they tend to be for players in the $1–2M range — veteran depth pieces who give a tight team a cheap useful player.

The team that loses a player on waivers can also lose them to a chain of waiver claims if the new team then puts the player on waivers themselves, but each claim is final until the player is again exposed.

Re-entry waivers (the rule that used to exist)

Before the 2013 CBA, the NHL had re-entry waivers: when a team called up a veteran who had cleared waivers and spent significant time in the AHL, they had to re-expose him on a different waiver list before he could play NHL games — and the claiming team only had to pay half his salary.

That rule was removed in 2013. Today, once a player clears waivers, he can be moved back and forth between the NHL and AHL freely for the rest of the season without going on waivers again, unless he plays a sufficient number of NHL games or his contract is later modified.

How teams use waivers strategically

At training camp

Every September, contending teams have to make hard roster decisions — keep a young player on the NHL roster (avoiding waivers) or send a veteran down (exposing him to claim). Teams often prefer to start the year with their best NHL roster even if it means risking a waivers claim later, because losing a veteran for free to a worse team is preferable to keeping the wrong player at the wrong cap hit.

Mid-season call-ups and demotions

Mid-season, teams shuffle players between the NHL and AHL constantly. Most movement is among waiver-exempt prospects, so no waivers issue. The hard calls come when a team wants to demote a struggling waiver-required veteran — they have to weigh the risk of a rival claim against the cap and roster benefit of the demotion.

At the trade deadline

The trade deadline includes a waiver wrinkle. Players claimed off waivers within a certain window before the deadline can't be re-traded at the deadline — the league prevents teams from using waivers as a backdoor trade chain. This affects how teams structure deadline-week roster moves and is one of the reasons you see flurries of waiver activity in the days right before the deadline.

The deadline cutoff is a specific date the NHL publishes each year; check league memos for the exact date in any given season.

Why the wire matters

Most fans never see the waiver wire mentioned in scoring summaries or highlight packages, but it shapes every team's bottom-six and depth chart. A team that nails a couple of waiver claims a year — a 4C, a third-pair D, a backup goalie — has effectively gotten free NHL talent. A team that loses a useful player to waivers because they had to choose between him and a younger asset has paid a quiet tax on their cap planning.

When you see depth-piece transactions happening in October or in the week before the deadline, the waiver wire is doing its work in the background.

The bottom line

Waivers are a free-agent market that operates inside the league all season long, ordered by reverse standings, settled in 24 hours, and structured to prevent NHL-caliber players from being hoarded in the minors. Every team has to think about waivers when they're building their roster — at camp, at midseason, and at the deadline.
