The Patriots have shown interest in defensive tackles during free agency, but Akiem Hicks chose Chicago over New England. Nick Fairley opted for the Saints after meeting with the Patriots.
Bill Belichick, Nick Caserio and their staff are still searching for some help for the interior of their defensive line, and while the pool of choices has thinned, they aren't yet totally dependent on the draft.
According to NFL Media's Ian Rapoport, the team is hosting defensive tackle Terrance Knighton on a visit Monday.
The 6-foot-3, 350-pounder is headed into his eighth professional season after spending last year with the Redskins. Knighton, who will turn 30 on the Fourth of July, accumulated 29 tackles and 1.5 sacks in 2015.
Knighton did not play in Washington's Week 9 loss to the Patriots -- it was the only game he missed last season -- but fans from this area remember Knighton (also known as "Pot Roast") for his performance in the AFC title game against the Patriots in 2013. He was part of a defensive line that handled the line of scrimmage in Denver, and he finished with one sack and four tackles -- all of which went for one yard or less.
Knighton spent two seasons with the Broncos after playing for the Jaguars during the first four years of his career. He was selected by Jacksonville in the third round of the 2009 draft.
A different player than Fairley, who has been one of the most effective pass-rushing defensive tackles in the league in recent years, Knighton (14.0 sacks in seven seasons) has been more of a run-stuffing defensive tackle over the course of his career.
Should the Patriots and Knighton strike a deal, he'd join a group of interior linemen that includes Malcom Brown, Alan Branch, Dominique Easley, Chris Jones, Frank Kearse, Ishmaa'ily Kitchen and Joe Vellano.
