Collingwood AFL player Dale Thomas has said on Twitter he is leaving the club, but the Magpies say the midfielder’s account has been hacked.

Thomas’ account tweeted on Wednesday: “thanks for the good times pies, decieded (sic) today that im not going to be here next year #futureandbeyond #carnnorrff #oobars”

But a club spokesman told AAP: “Daisy (Thomas) knew nothing about it. He’s been hacked.”

Hawthorn star Lance Franklin on Tuesday had his Instagram site hacked into, resulting in a fake admission that he had joined Greater Western Sydney.

A photo of the GWS logo appeared on his social networking account with the caption: “My soon to be new home”.

Hashtags including #moneyoverloyalty, #byealistair and #upthegiants were used in conjunction with it.

The photo attracted more than 1400 likes before it was deleted.
