Antonio Brown is still hoping to get back into the NFL, and recently he has been getting help from an NFL Hall of Famer. Deion Sanders posted on his Instagram that he's training with Brown. 

"My son came to town to work! On his game, on his life, on his thoughts, on his tomorrow and on Antonio Brown! I love him to life and I can't wait to witness this comeback story called 'A, B, and See.' I know what I know and pray you all get to see what I know to be true about Antonio Brown. God bless all y'all and please have a productive, peaceful day. We are growing and going!"

Sanders is the latest football player Brown has trained with this offseason. Brown has worked out with Baltimore Ravens quarterback Lamar Jackson and his cousin Marquise Brown, and caught passes from Washington Redskins quarterback Dwayne Haskins as recently as last week. Chad Johnson and Stefon Diggs were also reportedly in attendance. 

Brown had a workout with the New Orleans Saints last December, but nothing matriculated as he never was offered a contract. He last played with the New England Patriots in September, having four catches for 56 yards and a touchdown in his lone appearance with the team.  

Of course, Brown's receiving skills aren't what's holding up a potential NFL return. The Patriots released him following allegations of sexual assault, and the polarizing former Pro Bowler remains under investigation by the NFL for multiple off-field controversies.

If Brown were to sign with a NFL team, Roger Goodell has hinted he would likely end up on the Commissioner's Exempt List until its investigation into the sexual assault allegations is complete. This could potentially halt his signing with any team. 

Prior to joining the Patriots, Brown averaged 114 catches from 2013 to 2018, leading the NFL in receptions twice. He totaled 9,145 yards and 67 touchdowns, averaging 13.3 yards per catch during that span.
