As Hall of Fame quarterback Jim Kelly battles cancer for the second time in less than a year, many NFL officials and players have sent their respect and love to the former Bills star.

And at some point, one of his fellow Draft Class of 1983ers (and a fellow Hall of Famer) paid his respects in person. As posted Thursday on Instagram by Kelly's wife, Jill, when Dan Marino came to visit

In the caption, Jill Kelly wrote, "On the field. Off the field. Brothers. Memories and stories. Laughter and tears. Thank you #13 You're the only dolphin we love! #prayersforjk #NFL #DanMarino"

Kelly had been scheduled for surgery last week, but doctors determined that the procedure would not eradicate the cancer. Instead, Kelly will undergo chemotherapy and radiation treatments next week.

Last weekend, theMMQB.com's Peter King read 15-20 get-well tweets to Kelly, who said in response:
“Humbling. Humbling. I had no idea. I mean, I don't do Twitter, Instagram, Facebook, whatever. But they tell me about it. There's a lot of ‘Get well, Jim Kelly,' out there, and I am so appreciative of that. I really don't know what to say.”
