During training camp, Broncos quarterback Peyton Manning was taking snaps, wearing his usual preseason attire. With one exception: his towel had the name "Chris Crowson" on it.

Turns out Manning was paying a silent tribute to a young Broncos fan who died earlier in the summer. Chris Crowson was born on June 26, 1985 in Denver before his family moved to Raleigh, North Carolina, where he lived most of his life before it tragically ended too early during "unforeseen complications during surgery" in June.

Peyton's tribute was spotted on Reddit but not actually explained until Chris' father, Dan Crowson, joined "The David Glenn Show" in Raleigh last week to tell how Manning's tribute came to pass.

"As I understand it, [Chris' uncle in Denver] wrote a letter to Peyton to let him know Chris' love for the Broncos and respect for Peyton and what he was bringing to the Broncos," Dan said. "The way I found out was an email from the uncle in Colorado. He didn't know anything was going to happen.

"And then he got a package from Peyton with the towel with Chris' name on it, signed, with a picture of Peyton holding it."

How big a Broncos fan was Chris? His obituary describes him as "a goofy teddy bear with a heart of gold" but, more than anything, a huge Broncos fan.
