The time of Antonio Brown in Pittsburgh seems to be up.

Receiver Steelers Wide tweeted goodbye to Steeler Nation on Tuesday, while ensuring that an exchange on the part of the team that drafted it in the sixth round of draft 2010 is inevitable at this stage.

"Thank you SteelerNation for these 9 important years … It's time to go ahead ………." Brown wrote.

ESPN then reported that Brown had formally requested treatment.

The future of Brown has been the subject of speculation before the end of the regular season. He missed the Steelers 'last week of training and missed out on the Bengals' final in the midst of a quarrel with quarterback Ben Roethlisberger. His name has since shot in commercial rumors.

He was also charged with being involved in a family dispute in Florida in mid-January, although no charges were withheld. He has since asked for custody of his daughter following the alleged incident.

Brown was also found guilty of reckless driving after failing to appear in Pittsburgh court earlier Tuesday.

In nine seasons with the Steelers, Brown has amassed 837 catches for 11,207 yards and 74 touchdowns. He has been selected seven times in the Pro Bowl and four times in the first All-Pro team.
