The 25-year-old was entering the final year of his rookie contract. The new-money average of $18 million per season ties Hill for second among receivers with Odell Beckham Jr., according to Over the Cap. Michael Thomas' annual salary of $19.25 million tops the position.
Hill's status for the 2019 campaign was in doubt throughout much of the offseason due to allegations of child abuse involving his son. Hill also threatened his ex-fiancee in a recorded phone call.
The NFL decided not to punish the pass-catcher in July after completing "a comprehensive investigation."
"Local law enforcement ... publicly advised that the available evidence does not permit them to determine who caused the child's injuries. Similarly, based on the evidence presently available, the NFL cannot conclude that Mr. Hill violated the Personal Conduct Policy," the league said in a statement.
Hill is a vital cog in Kansas City's prolific passing attack. In 2018, he helped get the Chiefs to the AFC Championship Game with a 1,479-yard, 12-touchdown campaign that earned him first-team All-Pro honors.
