Knighton was released by the Patriots on Monday, Phil Perry of CSNNE.com reports.

EDGE Analysis

Knighton, who signed a one-year deal with Patriots back in March, had a tough time finding reps this preseason, as he failed to take the field against the Panthers on Friday. The veteran defensive tackle did play with the first-team at points during training camp, but has since found himself on the outside looking in behind the likes of Malcom Brown, Alan Branch, and Markus Kuhn. Knighton could attract offers from other teams who are looking to sure-up their defensive line before the season begins.
