The Denver Broncos are targeting Colin Kaepernick but they've also reached out to Ryan Fitzpatrick.

Fitzpatrick had an impressive 2015 with the New York Jets, but he remains a free agent.

"I believe that Colin Kaepernick is the target for the Denver Broncos," Silver said on NFL Network. "I believe the 49ers are amendable to trading him. Whether it is a (third-round pick) a (second-round pick) if that's what it takes. I think right now they're doing a dance. But I expect the Denver Broncos to go out and get Colin Kaepernick as their top option."
