90 Earl Mitchell DT

The 49ers didn't exercise their team option on Mitchell, making him a free agent, Matt Maiocco of NBC Sports Bay Area reports.

Reports first leaked shortly after the season indicating the 49ers didn't plan to pick up Mitchell's option, but the transaction didn't become official until the start of the new league year. The 31-year-old nose tackle is free to sign with any team after posting 17 tackles and no sacks across 14 games last season.

The 49ers will decline Mitchell's team option for the 2019 and 2020 seasons, allowing him to become a free agent in March, Ian Rapoport of NFL Network reports.

A run-stuffing tackle with just 6.5 sacks in 130 career games, Mitchell garnered 12 starts in his 14 appearances in 2018. The 31-year-old should draw some interest as an unrestricted free agent, though he'll likely have to settle for a reduction in both salary and role.

Mitchell (rest) did not practice Saturday, Cam Inman of The San Jose Mercury News reports.

The 49ers held Mitchell out of Saturday's organized activities to provide the veteran with added rest. There doesn't appear to be anything serious here, just a strategic rest day. Mitchell should be ready to go for the start of next week's team drills.

Mitchell recorded 33 tackles (19 solo) to go along with a sack in 16 games in 2017.

Fresh off inking a four-year contract last offseason, the veteran defensive tackle surpassed his previous career high in snaps that he set with Miami back in 2014. Primarily a run-stuffer, Mitchell didn't post totals that would appeal to IDP owners. His heavy usage indicates that the 49ers will likely feel comfortable deploying the 30-year-old in a similar early-down role next season.

Mitchell signed a four-year contract with the 49ers on Friday, NFL.com's Mike Garafolo reports.

Mitchell was cut by the Dolphins in a cap-saving move last week but it didn't take long for him to find a new home. While the Arizona product racked up a career-low 17 tackles and zero sacks last season, he could be in line for a rebound in 2017 if he can secure the Niners' first-string nose tackle job this summer; the incumbent starting nose tackle, Glenn Dorsey, is set to hit unrestricted free agency.

Mitchell was released by the Dolphins on Thursday, Armando Salguero of the Miami Herald reports.

Mitchell was scheduled to earn $4.5 million in 2017, of which the Dolphins save $4 million by cutting him. The defensive tackle shouldn't be out of a job for long, however, as he is very talented and is an asset when it comes to stopping the run. With Mitchell gone, Jordan Phillips is expected to take over as the Dolphins' starting defensive tackle next to Ndamukong Suh (knee).

Mitchell (calf) was activated from injured reserve Thursday, Hal Habib of the Palm Beach Post reports.

As expected, Mitchell returned to the active roster after being placed on the IR in Week 1 of the season. The team has yet to comment on how much, if any, action the defensive tackle will see this Sunday against the Chargers. His calf injury will be something to keep an eye on if he does receive some defensive reps, as he figures to serve as the primary backup behind starter Jordan Phillips.

Mitchell (calf) could be activated off of IR and play Sunday in San Diego, Adam Beasley of the Miami Herald reports.

Head coach Adam Gase stated Monday that Mitchell will be activated if he comes through practice this week without any setbacks. Mitchell would be a boost to a linebacking corps that has had it's share of injuries and will go up against one of the best backs in the NFL on Sunday in Melvin Gordon.

Mitchell (calf) could be ready to play in two weeks, Armando Salguero of the Miami Herald reports.

Mitchell was placed on IR earlier this season after suffering the calf injury. He may not start upon is role but is expected to help out at inside linebacker.

Mitchell (calf) was placed on injured reserve Tuesday, Mike Garafolo of NFL Network reports.

Mitchell could be available to return midway through the season with the return rule now in place. The defensive end suffered a calf injury prior to Sunday's game, but is only considered week-to-week. With Mitchell out for the foreseeable future, Jordan Phillips, Julius Warmsley, and Ndamukong Suh will be the only healthy defensive tackles on the roster.

Mitchell is considered week-to-week with a calf injury, Barry Jackson of the Miami Herald reports.

Mitchell dealt with a lingering calf injury prior to Week 1, but was cleared before the game for a return to the field. He appeared to have aggravated his existing injury during the contest and is now dealing with some lingering pain. He's considered week-to-week, but we should see his status for Saturday's matchup against the Patriots updated as game day approaches. Jordan Phillips and Julius Warmsley are the likely beneficiaries of playing time if Mitchell sees an extended absence.

Mitchell is questionable to return to Sunday's game due to a calf injury.

Mitchell was hobbled by a calf injury during the preseason but was deemed ready to play heading into Sunday's contest. His exit from the game was likely due to tweaking the calf, so if he's unable to return, expect Jordan Phillips and Julius Warmsley to pick up additional snaps.

Mitchell (calf) is active for Sunday's matchup against the Seahawks.

As expected, Mitchell will suit up for the Dolphins' regular season opener despite returning to practice just this week. However, he'll operate under a restricted snap count. For this reason, backup DTs Jordan Phillips and Julius Warmsley will likely see an uptick in playing time.

Mitchell (calf) will have his snaps monitored Sunday in Seattle, Armando Salguero of the Miami Herald reports.

While the good news is that Mitchell will play Sunday, the bad news is that he won't be a three-down player as the Dolphins look to make sure he will be healthy for the long haul.

Mitchell (calf) returned to practice on a limited basis Monday, Armando Salguero of the Miami Herald reports.

Mitchell has missed a couple of weeks due to the injury but his return to practice is a positive sign and he would seem likely to play Sunday in Seattle.

Mitchell (calf) will not play in Thursday's preseason game, Chris Perkins of the South Florida Sun-Sentinel reports.

Mitchell's calf ailment is not expected to keep him sidelined for Week 1. The 28-year-old has stood out this offseason and projects to start as an interior defensive lineman for the Dolphins in 2016.

Mitchell (calf) is progressing in his injury recovery and expects to be ready for Week 1 of the regular season, James Walker of ESPN NFL Nation reports.

Mitchell sounds optimistic regarding his status moving forward as he remains on the journey back to full health. The Dolphins begin their season Sept. 11 against the Seahawks, and Mitchell hopes to be on the field next to fellow defensive tackle Ndamukong Suh.

Mitchell missed practice Tuesday due to a calf injury, Armando Salguero of the Miami Herald reports.

There is no word as of yet to the severity of the injury or to how long Mitchell may be out of action for. Mitchell is expected to be part of the defensive line rotation for Miami this season.

Mitchell (calf) is inactive Sunday against the Patriots.

Despite putting in limited practices on Thursday and Friday, Mitchell will miss his third game in a row. In his absence, Jordan Phillips is likely to see extensive action at right defensive tackle.

Mitchell (calf) won't play Sunday in San Diego, reports the Miami Herald's Armando Salguero.

Mitchell aggravated his calf during the loss Monday to the Giants. His loss Sunday shouldn't be a big one for Miami as the Chargers are much more dangerous with the pass than they are with the run.
