The Patriots signed defensive tackle DaQuan Jones on Saturday, adding a veteran with experience in Mike Vrabel's defense while moving wide receiver A.J. Brown to injured reserve. New England used the opening on its roster to reinforce the middle of the defensive line ahead of its September 20 home opener against Pittsburgh.

Jones arrives on a reported one-year agreement with a $3.5 million base value and a maximum of $6 million, according to NFL Network's Ian Rapoport. The Patriots confirmed the signing but did not disclose financial terms. The reported contract value should not be treated as a verified salary-cap charge or a fully guaranteed amount.

Rapoport's original report outlines the proposed deal before the team announced the signing.

Another option at nose tackle

Jones played for Vrabel in Tennessee from 2018 through 2020. The 34-year-old has since played for Carolina and Buffalo, and the Patriots credit him with 167 regular-season appearances and 161 starts.

That history gives New England a familiar option for work in the middle. The team's analysis says more than 62 percent of Jones' snaps in his final Tennessee season came over the center or in the adjacent gap. Cory Durden has been handling that nose-tackle role following Khyiris Tonga's departure.

The signing does not establish a new starting order. Pats Pulpit's roster review counted six active defensive tackles after the move, with Jones joining Durden, Milton Williams, Christian Barmore, Joshua Farmer and Leonard Taylor III. The game-day rotation will reveal how much work the addition changes for the other five.

The roster opening does not replace Brown's production

Jones brings more than size. The Patriots' analysis credited him with three sacks, 25 pressures and nine run stuffs for Buffalo last season, evidence of contributions against both the pass and run.

Brown's move has a separate consequence for managers tracking New England's offense: the receiver must miss at least four games. Adding Jones fills the roster spot but leaves the receiving work to be redistributed among players already available to the offense.

The immediate checkpoints are therefore different on each side of the ball: Jones' share of the interior defensive snaps, and how the passing game operates without Brown. The Steelers visit is scheduled for September 20 at 1 p.m. Eastern on CBS.
