Dumervil announced his intent to retire, Nicki Jhabvala of The Athletic Denver reports.

EDGE Analysis

The Louisville product's career began in Denver after he was selected in the fourth round of the 2006 NFL Draft. Since entering the league, Dumervil has racked up 105.5 career sacks, 63.5 of those coming in the Mile High City. Following six seasons with Denver, Dumervil also made a four-year pit stop in Baltimore before spending his final season in the Bay Area.

The 49ers informed Dumervil that he will not be retained for the 2018 season.

EDGE Analysis

Dumervil joined the 49ers on a two-year, $8 million deal last offseason and produced 13 tackles and 6.5 sacks in 16 games. It's somewhat surprising the 49ers cut ties with the 34-year-old given his relatively small cap hit, but his absence will allow the team to give more playing time to its stockpile of first-round defensive lineman in Soloman Thomas (2017), DeForest Buckner (2016) and Arik Armstead (2015).

Dumervil recorded two solo tackles and one sack in Sunday's win over the Bears.

EDGE Analysis

The veteran now has 10 tackles and 5.5 sacks in his first season by the bay. What may be even more impressive is the fact that he reached Sunday's totals while only logging 14 snaps defensively, his second-lowest snap count of the season. He'll now turn his focus to Sunday's matchup with the Texans.

Dumervil brought his sack total up to 4.5 in Sunday's victory over the Giants.

EDGE Analysis

Dumervil saw a season high 37 snaps due in large part to the absence of Solomon Thomas (knee). While the seasoned pass-rush specialist was able to notch another sack, it was his only tackle of the contest, and he only has seven total tackles this season to go along with his 4.5 sacks. Dumervil will continue to only see work on passing downs, which limits his appeal in IDP formats that do not place high importance on accruing sacks.

Dumervil finished with three tackles (two solo) and 1.5 sacks in a 26-23 loss to the Colts on Sunday.

EDGE Analysis

Dumervil has now collected 3.5 sacks over his last two contests after failing to record a tackle or a sack over the previous three games. The veteran pass rusher has yet to eclipse the 30-snap mark in any game this season, which severely limits his tackle potential on a weekly basis. Dumervil's sack streak may be in jeopardy when the 49ers take on two of the better offensive tackles in the NFL -- Trent Williams and Morgan Moses -- next week in Washington.

Dumervil recorded two sacks in Sunday's loss to the Cardinals. They were his only tackles on the day.

EDGE Analysis

The veteran pass rusher was only on the field for 33 percent of the team's defensive snaps, but he made them count, getting to Carson Palmer twice and reaching the impressive milestone of 100 sacks over his nine-year career. Dumervil will continue to be used exclusively as a pass-rush specialist, limiting his tackle total -- and in turn -- his IDP value going forward.

Dumervil signed a contract with the 49ers on Monday, Conor Orr of NFL.com reports.

EDGE Analysis

The veteran heads to San Fran to play alongside a young core of pass rushers. Dumervil, 33, appears likely to take on a rotational rusher role but will also serve as a mentor to the likes of 2017 third-overall pick Solomon Thomas, 2016 first-round pick DeForest Buckner and 2015 first-round pick Arik Armstead. Dumervil, a five-time Pro Bowler, missed eight games with the Ravens last season due to a foot injury. He played with current 49ers GM John Lynch early on in his career with the Broncos and now sits at 99 career sacks over 11 seasons.

Dumervil will be released by Baltimore, Steve Smith Sr. of NFL Network reports.

EDGE Analysis

Dumervil missed eight games in 2016 due to a foot injury, finishing the year with just 11 tackles, including 3.0 sacks, both career lows. He'll be an unrestricted free agent upon his release. The 10-year veteran will be entering his age-33 season in 2017.

Dumervil (foot) is active for Sunday's game against the Titans, ESPN.com's Jamison Hensley reports.

EDGE Analysis

Dumervil's foot injury had kept him sidelined for the Ravens' previous four games, but after the veteran was a full participant in all three of the team's practices this week, he'll be cleared to take the field for the first time since Oct. 9. He may only see limited snaps in his return to action, however, as Jeff Zrebiec of the Baltimore Sun reports that Terrell Suggs and Albert McClellan are expected to continue starting at outside linebacker, with Dumervil likely entering the contest primarily on passing downs.

Dumervil (foot) is questionable to play Sunday against the Bengals, CSN Mid-Atlantic reports.

EDGE Analysis

Dumervil was a full participant in every practice this week, so his status for Sunday's game realistically doesn't appear in danger.
