67 Ted Karras C

Karras agreed Wednesday with the Dolphins on a one-year, $4 million contract, Jeremy Fowler of ESPN.com reports.

The retooling of the Dolphins' offensive line continues, with Karras -- a 2016 sixth-rounder -- now slated to start at center alongside guard Ereck Flowers, whom the team agreed to a deal with Tuesday. Karras, 27, made 20 starts over 60 appearances with the Patriots the past four seasons.

Karras (knee) is active for Sunday's game against the Bengals.

Karras is expected to start at center in this game.

Karras (knee) is listed as questionable for Sunday's matchup with the Bengals.

Karras missed last week's loss to the Chiefs and is in danger of missing another. James Ferentz will be in line to replace him at center should he ultimately not be able to suit up.

Karras (knee) will not play in Sunday's matchup with the Chiefs.

Karras is dealing with an MCL sprain, so it comes as no surprise that the Patriots will opt to err on the side of caution here. In his absence, James Ferentz will presumably handle center duties.

Karras was diagnosed with a sprained MCL on Tuesday, Jeff Howe of The Athletic reports.

The 26-year-old seems likely to be sidelined for Sunday's game against the Chiefs, but since it appears to be a minor sprain he may not be forced to miss additional time. James Ferentz is the likely starter at center in Karras' expected absence.

Karras will have an MRI to after suffering a knee injury during Sunday's 28-22 loss to the Texans, Ian Rapoport of NFL Network reports.

The team fears Karras has a sprained MCL, which would likely rule him out for Week 14's matchup against the Chiefs. James Ferentz took over at center for the remainder of the contest and figures to start in the aforementioned contest if Karras' injury is confirmed.

Karras has suffered a knee injury and won't return to Sunday's game in Houston.

Karras was the only player to play every offensive snap for New England this season, but that streak has been brought to an end by this injury. James Ferentz took over for him at center.

Karris joined the Patriots' 53-man roster Thursday, Mike Reiss of ESPN.com reports.

Karras takes the roster spot of wide receiver Malcolm Mitchell, who was placed on injured reserve. Barring injury, the 2016 sixth-round pick will likely remain a depth option for New England this season.
