Grier and head coach Mike McDonald met on Monday to have a discussion regarding the matter. Hill told the media that he practically wants out of Miami and that he's ready for his next move.
"They were (productive) conversations," said Grier at the team's end-of-the-year press conference.
"I will keep those between us. The one thing I would say is, in a frustrating season, he was very emotional in a game where we had a chance, coming back from 2-6. All of that with him playing through his (wrist) injury just kind of bubbled to a point.
"I was very direct with him," said McDonald after meeting with Hill to discuss everything. "He was very honest, and it was great terms that we were discussing."
Hill later posted a photoshopped image of his face over former NFL wide receiver Antonio Brown's body; during the game he took off his jersey and pads and left before the game ended. He later changed it back to his regular profile picture.
"We discussed multiple things, including without wavering, that it's not acceptable to leave a game and won't be tolerated in the future, and he embraced accountability. I wouldn't say there's necessarily anything to fix, but we had to clear the air in a rough and tumultuous situation."
Hill's 939 receiving yards this season are the fewest since 2019 when he put up 860 yards. His six receiving touchdowns are also the lowest since his rookie season in which he put up the same amount.
This is also the first season in which Hill did not make the Pro Bowl after earning a spot in the first eight years of his career. Hill has also earned All-Pro honours the past two years and five times in his career, but will probably miss out on that as well after the season he had.
Hill also had a run-in with the law earlier this season after being handcuffed during a traffic stop.
He is currently on a three-year, $90 million deal with the Dolphins and is under contract for the 2025 season, but has an opt-out option for 2026. He has a $28.6 million cap hit for next season, according to Spotrac.
