Pittsburgh Steelers general manager Kevin Colbert says three teams have reached out so far about potentially trading for star wide receiver Antonio Brown.

Colbert, who spoke with NFL Network on Friday, did not however divulge any of the teams that he's been in contact with.

A source told ESPN's Jeremy Fowler that Pittsburgh would prefer to send Brown out of the AFC conference and over to the NFC for competitive reasons. Fowler also reports that the reigning Super Bowl champion New England Patriots as well as the AFC North, the division that the Steelers are a part of, are considered no-trade zones.

After a tumultuous end to the regular season that saw Brown made inactive by the Steelers for their Week 17 matchup against the Cincinnati Bengals, as well a series of cryptic tweets sent out by Brown this off-season, the Steelers officially put the wide receiver on the trading block on Tuesday after he met with team owner Art Rooney II.

Brown, who was named Pro Bowler for the sixth consecutive season in 2018, recorded 104 receptions for 1,297 receiving yards and 15 touchdowns with the Steelers.
