Montreal Alouettes quarterback Anthony Calvillo underwent a complete thyroidectomy on Tuesday after pathology results revealed the presence of some cancer cells.
Dr. Roger Tabah, who performed the surgery in Montreal, said the procedure went well and there were no surprises.
Calvillo faces a single treatment of radioactive iodine therapy in January and will be treated with thyroid hormone replacement medication in the future.
It is expected he can resume working out in February and be at the start of training camp next June.
Calvillo initially had surgery last week because of a suspicious lesion on his thyroid gland.
