Yannick Ngakoue expressed his frustration with the Jacksonville Jaguars on social media on Monday.

Ngakoue called the team owner's son a clown and urged the team to get "this s--- done."

The exchange between Ngakoue and Tony Khan, the son of owner Shad Khan and the team's senior vice president of football administration and technology, began with Ngakoue's tweet that said only: #FREEYANN. Moments later, Ngakoue told Tony Khan to stop hiding.

Ngakoue's battle with the Jaguars began last July when then-executive VP of football operations Tom Coughlin abruptly broke off negotiations with Ngakoue and his agent, Ari Nissim.

Ngakoue was reportedly offered a contract that would pay him $19 million annually.

The Jaguars applied the non-exclusive franchise tag to Ngakoue on March 13, and he would earn $17.8 million in 2020.

The Jaguars are seeking at least one first round pick for Ngakoue.
