The Patriots are activating offensive tackle Calvin Anderson from the non-football illness list Tuesday, ESPN’s Field Yates reported.

Anderson has missed all of training camp on the NFI list and now is set to return to practice less than two weeks ahead of the Patriots’ season opener against the Philadelphia Eagles.

If Anderson had stayed on NFI, then he would have been forced to miss the first four weeks of the season.

Anderson has been a regular at practice wearing sweats. He has not practiced with the team since June during organized team activities and minicamp. There’s no guarantee that he’ll be ready for Week 1, but this move does make him available.

The reason for Anderson’s placement on the NFI list are undisclosed. He joins Trent Brown, Riley Reiff, Sidy Sow, Andrew Stueber, Tyrone Wheatley Jr. and Vederian Lowe among the Patriots’ available offensive tackles. The Patriots still have 26 roster moves to make by Tuesday at 4 p.m. to get down to 53 players.

The Patriots also still have Cole Strange, David Andrews, Mike Onwenu, Jake Andrews, Atonio Mafi, James Ferentz, Conor McDermott, Bill Murray and Kody Russey on their roster among interior offensive linemen.
