There's growing trade interest in Pittsburgh Steelers receiver Antonio Brown, and the Oakland Raiders, Denver Broncos, and Arizona Cardinals appear the most intrigued, NFL Network's Ian Rapoport reports.

The Raiders have often been mentioned as potential suitors, as they have both the draft picks (three first-round selections) and the cap space ($72 million) available to acquire such a talent.

Arizona owns the first and 33rd picks in the draft and appears to be interested in expediting its rebuild, as exemplified by its retention of Patrick Peterson.

The Broncos are a new name tied to Brown, but they fit the criteria as a team outside the AFC North. The Steelers won't play the AFC West again until 2022.

However, Mike Klis of 9News and Nicki Jhabvala of The Athletic report that sources have told them Denver is not interested in acquiring Brown.

Brown is due a $2.5-million roster bonus on March 17, though Rapoport reports there is enough interest for a trade to happen before then.
