Tyreek Hill has established himself as one of the most explosive wide receivers in the NFL. Now he's one of the game's highest-paid wideouts, too.

Hill and the Kansas City Chiefs agreed to a three-year, $54-million extension Friday, a person with knowledge of the situation told USA TODAY Sports' Mike Jones. The person spoke on condition of anonymity because they were not authorized to disclose terms of the deal.

The $18 million per year ties him with Cleveland Browns' Odell Beckham Jr. for second among all wide receivers in annual average salary, while both trail Michael Thomas of the New Orleans Saints in that respect.

Hill is guaranteed $35 million and, according to reports, will receive a $5.8 million signing bonus.

Hill was set to become an unrestricted free agent after this season and was entering the final year of his rookie deal that paid him slightly north of $2.5 million over four years.

During the offseason, an 11-minute audio clip — not independently authenticated by USA TODAY Sports — aired by Kansas City TV station KCTV5 revealed an argument between Hill and his fiancée Cystal Espinal at the Dubai airport on how the couple's 3-year-old son broke his arm.

Johnson County District Attorney Steve Howe closed an investigation after saying he did believe the boy was hurt but that he could not prove who had injured the child.

The NFL conducted its own investigation into child abuse accusations but ultimately did not discipline him. The Chiefs suspended him from team activities during the probe, but he returned to training camp after the league issued its ruling. He was dismissed from the Oklahoma State football team in 2014 for allegedly choking Espinal, to which he pleaded guilty to domestic assault and battery.

On the field, however, Hill has been dynamic. A key threat both as a receiver and a returner, Hill has scored 33 touchdown in his first three years in the league. He averaged 92.4 receiving yards per game last year, as well as 15 yards per touch.
