He also missed part of a season while he was undergoing treatment for cancer, which not only further endeared him to the Kansas City fan base but also to the National Football League community at large.
By releasing Berry, the Chiefs don't have to pay him an additional $7.25 million that would have become guaranteed by Friday.
Berry, 30, joined the Chiefs in 2010 as a first-round draft pick (fifth overall) from Tennessee and established himself as one of the NFL's top safeties.
He tore his Achilles' tendon in the 2017 opener, sidelining him the rest of the season. But he's been off the field for most of the last two seasons with injuries.
Berry has recorded 440 tackles (372 solo), 5.5 sacks, 14 interceptions (five returned for touchdowns), 51 passes defended, three forced fumbles and two fumble recoveries during his career. He made the Pro Bowl in his rookie season.
He also earned the team's Derrick Thomas Award in 2015 and 2016, given to the team's most valuable player, voted on by his teammates. "He's a special person, and we wish him the best as his career moves forward".
The greatest moment of Eric Berry's storied tenure as a Chief happened prior to kickoff in a playoff game the Chiefs ultimately lost.
The team also recently released linebacker Justin Houston, freeing up $21.1 million in their salary cap.
The move comes following Kansas City's agreement with Tyrann Mathieu on a three-year, $42 million contract.
