Head coach Andy Reid and the Kansas City Chiefs were hit hard with fines and the loss of two draft picks after the NFL said the team tampered with Jeremy Maclin during the 2015 free-agency period.
The Chiefs will be docked a third-round pick in the 2016 NFL Draft and a sixth-round pick in the 2017 NFL Draft, it was announced on Wednesday.
On top of that, Reid has been fined $75,000, general manager John Dorsey was fined $25,000 and the team as a whole was hit with a $250,000 fine.
Chiefs chairman and CEO Clark Hunt said the team will appeal.
"Today we were informed by the National Football League that our club will be disciplined for an infraction during the 2015 free agency negotiating period," Hunt said in a statement.
"While we respect Commissioner Goodell and the process, we believe that the penalties proposed in this case are inconsistent with discipline enforced in similar matters - particularly given the league's inconsistent communication of its policies on contact with potential free agents.
"As an organization, we take great care to conduct ourselves with integrity and operate within the guidelines of the NFL. We have been fully cooperative and transparent with the league in this matter, and we are disappointed with the league's decision. I want to make it clear that I fully support the leadership of both Coach Reid and John Dorsey. We will continue to explore our options under the appeal process."
Maclin was still under contract with the Philadelphia Eagles during the negotiation period when the contact occurred. During that time, coaches and teams have to go through the player's agent and not have direct contact with him.
Maclin eventually signed with the Chiefs for five years, $55 million.
According to NFL executive vice president of football operations Troy Vincent, the punishment could have been worse were it not for the fact the Chiefs had never violated the tampering rule.
The Chiefs also fully cooperated with the NFL when they began the investigation into the tampering, which helped make their punishment less severe.
