Manchester United tweeted:
Rio Ferdinand has spoken of his sadness at not being able to say goodbye properly before his departure from Manchester United.
The veteran defender issued a statement saying: "Circumstances didn't allow for me to say goodbye the way I would have liked but I'd like to take this opportunity to thank my team-mates, staff, the club and the fans for an unbelievable 12 years that I'll never forget.
Veteran defender Rio Ferdinand will leave Manchester United this summer after 12 years at the club.
Ferdinand's contract had come to an end and the club have opted not to renew the 35-year-old's deal.
He said in a statement: "I have thought long and hard over the last few months about my future and, after 12 fantastic years playing for what I regard as the best club in the world, I have decided the time is right for me to move on."
The centre-back joined the Old Trafford outfit for £30m from Leeds United in the summer of 2002, going on to make over 300 appearances.
England manager Roy Hodgson and Manchester United defender Rio Ferdinand have joined Football Association chairman Greg Dyke's England commission.
The appointments were announced a day after FA board member Heather Rabbatts publically criticised Mr Dyke for a lack of diversity on the commission.
The FA can confirm Roy Hodgson and @rioferdy5 have agreed to join The FA Chairman Greg Dyke's England Commission.
Answering a question from ITV News Sports Editor Steve Scott, the midfielder said: "I'm not interested in what Rio Ferdinand has to say about this group of players.
"When you play for England there's always a lot of opinions outside the group, especially in a World Cup year...but when we're inside (the group) we don't take much notice of what is said outside."
He added that he disagreed with Ferdinand's comments and felt the current England squad did have an identity.

Manchester United star Rio Ferdinand said today's 5-5 draw with West Brom was "a mad result", but pondered that Sir Alex Ferguson's last game as manager was never going to be a boring one:
5-5.....what a mad result! Lets be honest the boss was never going out with a boring 0-0!!
It is important to pay tribute to someone of Rio’s stature and the achievements he had in a senior international career with England over 14 years at the highest level.
To have captained his country, to play at three World Cups and indeed score in one of those, marks him out amongst a very special group of players.
I appreciated the call from Rio to inform me of his decision, which clearly he had spent much time considering before reaching this point.
I wish him all the best in his club career, and I’m sure the former managers he played under and every England fan will join me in thanking him for his service.
After a great deal of thought, I have decided the time is right for me to retire from international football.
At the age of 34, I feel it is right for me to stand aside and let the younger players come through, which allows me to concentrate on my club career.
The team looks in great shape and there is an influx of young, talented players coming through the ranks which bodes well for the future.
I regard it as a great honour and a privilege to have represented my country at every level from U17s upwards.
I have always been very proud to play for England. I would like to wish Roy and the team all the best for future tournaments.
A big thank you to all the fans, managers, coaching staff and players that I have worked alongside - the journey has been incredible.
