The New England Patriots made a few moves Monday, placing offensive lineman Tre' Jackson on the reserve/physically unable to perform list, and waiving defensive lineman Terrance Knighton and center Bryan Stork.
The second-year Jackson was active his rookie season in 2015, starting nine games and appearing in 13 total games at right guard during the regular season. But he sat out both playoff games with a knee injury.
Jackson was projected to be in line to start in 2016, but he was never a full participant during training camp.
Stork was traded to Washington last week for an undisclosed draft pick. His rights reverted back to the Patriots on Monday after he reportedly failed his physical.
He played 21 games with 17 regular-season starts and four starts in the postseason with New England. Stork also started the Patriots' Super Bowl victory over the Seattle Seahawks.
The seven-year veteran Knighton signed with the Patriots this offseason in April, but became buried on the depth chart during camp. Coach Bill Belichick said the decision to cut ties with Knighton had to do more with numbers than anything.
"I don't know. It just didn't work out," Belichick said. "The kid came in and worked hard. Lost weight. Got in good condition, tried to do the things we asked him to do. Other people ahead of him."
