MIAMI -

Dan Marino paid a visit to Jim Kelly who is continuing his fight with cancer.

Kelly posted an image of the visit on instagram.

Kelly wrote, "On the field.  Off the field.  Brother.  Memories and stories.  Laughter and tears.  Thank you #13.  You're the only Dolphin we love!  #prayersjk #NFL #DanMarino."

The two were rivals on the field for years.

The Bills and Dolphins with so many great showdowns.

But as Kelly continues to fight for his life, his former opponent is giving a strong show of support.

Kelly was scheduled to have surgery.

However, his wife said, doctors cancelled the operation.
