Sources: Marcus Cannon has cancer

TCU offensive lineman Marcus Cannon has a treatable form of lymphoma that was discovered in the run-up to the NFL draft, sources tell ESPN NFL Insider Adam Schefter.

A source told ESPNDallas.com that Cannon was diagnosed with a benign growth in his groin area over four years ago, but physicals for the draft revealed that it had grown. A biopsy and further tests revealed that the 6-foot-6, 350-pound senior has non-Hodgkin lymphoma.

Cannon's representatives have released a medical report to all 32 NFL teams, sources told Schefter.

Cannon will begin chemotherapy Wednesday and will have three more treatments over the next three months and be finished by June 29. Because of his age and health, Cannon faces a success rate for beating the cancer of more than 90 percent.

The NFL draft begins Thursday, and ESPN's Todd McShay has Cannon ranked as the 11th best offensive lineman in the nation.
