Patriots rookie offensive tackle Marcus Cannon was added to the active roster from the reserve/non-football injury list on Tuesday. Tuesday marked the deadline for players who started the season on the PUP list to be activated. The 6-foot-6, 348-pound Cannon, the team's fifth-round draft choice out of TCU, said last month that he's in full remission from non-Hodgkin's lymphoma. Patriots director of player personnel Nick Caserio offered high praise for the doctors and trainers who worked with Cannon the past three months to put him in position to join the active roster. "Like we talked about back at the draft, football was the least important thing for him, in terms of getting healthy, at that point," Caserio said. "Look, we'll add him to the mix, put him on the roster. He'll be no different than any other player. We'll ask him to do the same things -- work on fundamentals, prepare to play. When is he going to play? Nobody knows at this point, but the expectation is for him to work hard, prepare to play."
