Parker announced via his personal Twitter account that he's retiring.

EDGE Analysis

Parker spent his first two seasons in the league between the Seahawks, Raiders and Panthers before signing with the Chiefs in 2013. He spent another year as a reserve before taking over as a starting safety for the next five seasons until he was cut following the 2018 campaign. Parker posted 397 tackles, eight sacks, 48 pass breakups and 11 interceptions in his career.

Parker was released by the Chiefs on Tuesday, Terez A. Paylor of Yahoo Sports reports.

EDGE Analysis

Parker's release comes as a bit of a surprise after he played nearly 90 percent of the team's defensive snaps this season, though he was a healthy scratch near the end of the year. His release coincided with the promotion of offensive guard Laurent Duvernay-Tardif. Parker will become a free agent and, barring he's signed by one of the other three remaining playoff teams, set his sights on making another roster in 2019.

Parker is inactive for Sunday's game against the Seahawks, Adam Teicher of ESPN.com reports.

EDGE Analysis

Parker did not appear on Kansas City's injury report this week, making him a healthy scratch for Week 16. Jordan Lucas will draw the start at free safety versus Seattle, opposite veteran Eric Berry.

Parker recorded eight tackles (seven solo) and one pass defended in the Chiefs' 54-51 loss to the Rams on Monday.

EDGE Analysis

In one of the highest scoring games in NFL history, Parker was one of the lone bright spots for the Chiefs defense Monday. The 31-year-old safety was able to lead the team in tackles and keep up his stellar 5.2 tackles per game average. Parker and the Chiefs will be on bye this week.

Parker totaled two tackles and one sack during Sunday's victory over Arizona.

EDGE Analysis

Parker hasn't been used as a pass-rusher much over the last couple of seasons, but he was able to take down quarterback Jared Goff in what marked the veteran's first sack since 2015. While Parker's overall tackle total was a disappointment, he entered the game averaging 5.2 tackles per game and should have a good chance of reaching higher production in a Week 11 showdown against the Rams.

Parker made nine tackles (six solo) in Sunday's 43-40 loss to the Patriots.

EDGE Analysis

More pressure was on Parker this week while Eric Berry (heel) and Eric Murray (lower leg) sat out. Parker's performance ties his season-high for tackles, and he could be relied on again in Week 7 against the Bengals if Berry and Murray can't shake their injuries.

Parker is signing with the Chiefs, Terez A. Paylor of Yahoo Sports reports.

EDGE Analysis

After spending most of his career with the Chiefs, the 31-year-old safety signed a one-year contract to join the Falcons in June. He was then released by Atlanta on Friday, paving the way for a return to Kansas City, where injuries have taken a toll at safety. Parker figures to open the season in a reserve role.

Parker was released by the Falcons on Friday, D. Orlando Ledbetter of the Atlanta Journal-Constitution reports

EDGE Analysis

Parker signed with Atlanta this offseason after logging over 1,000 defensive snaps for the Chiefs in each of the past four years. However, the veteran became expendable after the Falcons acquired fellow safety Jordan Richards from the Patriots on Friday. Now an unrestricted free agent, Parker shouldn't have much trouble finding a new home.

Parker agreed to a one-year contract with Atlanta on Monday, Vaughn McClure of ESPN.com reports.

EDGE Analysis

The Falcons add depth to their secondary with the signing of Parker, an experienced player who has taken snaps at cornerback, free safety and strong safety in his seven professional seasons. The 30-year-old defensive back had brief stints with the Raiders, Seahawks and Panthers at the beginning of his career, but he made a name for himself in Kansas City where he played in all 80 of the team's games since 2014 (with 64 starts), accumulating 279 tackles and nine interceptions during that span. Parker became dispensable for the Chiefs after enduring his worst season as a pro, compiling just four pass deflections after picking up 12 in each of the previous three years, while his overall performance ranked 84th out of 87 qualified safeties in 2017, per Pro Football Focus.

The Chiefs are expected to release Parker this offseason, Terez A. Paylor of the Kansas City Star reports.

EDGE Analysis

Parker, who's approaching his age-31 season, is still a solid player and was likely released for financial purposes given the fact the Chiefs save roughly $5 million in cap space with his release. While he had disappointing troubles in both run support and pass defense during the 2017 campaign -- ultimately grading out as Pro Football Focus' fourth-lowest graded safety out of 89 qualifiers -- the Newberry product was better in his previous three seasons with Kansas City, racking up 300 tackles, 40 pass breakups and seven interceptions in 63 games. Those numbers would rank fourth, first and second, respectively, among this year's free-agent class of safeties.
