The Denver Broncos, New York Jets and Cleveland Browns have all expressed interest to the San Francisco 49ers in trading for Colin Kaepernick.

Nothing is imminent at this point.

The Broncos have a void at quarterback after the free-agent defection of Brock Osweiler to the Houston Texans and the retirement of Peyton Manning.

The Jets are in a stalemate with Ryan Fitzpatrick.

Kaepernick's agents requested permission from the 49ers on Feb. 26 to seek a trade for their client.

Kaepernick is recovering from surgeries to his left shoulder, right thumb and left knee, and on April 1 his $11.9 million base salary for 2016 becomes guaranteed.
