OL Cannon to active/NFI

As part of their transactions made on Friday, the Patriots placed rookie offensive lineman Marcus Cannon on the active/non-football injury list, according to a league source.

The fifth-round selection, who underwent treatment for non-Hodgkin's lymphoma earlier this year, officially signed his rookie contract with the team today.

Cannon finished his chemotherapy treatments earlier this month. He was seen at Friday afternoon's practice working with the team's strength and conditioning staff on the sidelines.

By placing Cannon on the active/NFI list, he is able to return to practice at any time. If Cannon does not return to action by the 53-man roster cutdown date (Sept. 3), the team will have the option of placing him on the Reserve/Non-Football Injury list, which would sideline Cannon for at least the first six weeks of the regular season.

In addition, there is one clarification to pass along regarding Friday's transactions. Undrafted rookie linebacker Ryan Coulson was waived/injured, meaning that if Coulson clears waivers, he will revert to the team's injured reserve list. Coulson did not finish Thursday afternoon's practice after suffering an injury late in the session.
