Danish Kaneria plans to appeal against the lifetime ban handed down to him by an England and Wales Cricket Board Disciplinary Panel for his role in a spot-fixing plot.
The 31-year-old spinner was found guilty of "cajoling and pressurising" former Essex team-mate Mervyn Westfield into accepting cash in return for trying to concede a set number of runs in an over during a Pro 40 match in 2009.
In announcing the punishment, the ECB panel desribed Kaneria as a "grave danger" to the sport while describing his evidence during the four-day hearing in London as "plainly lies".
But speaking to Sky Sports News HD, Pakistan's fourth-highest Test wicket-taker maintained his innocence, insisting it was a "very, very unfair decision".
"I'm very upset about this decision. For what reason they have convicted me I do not know," he said.
"It is a very, very unfair decision against me. I've come all the way from Pakistan to say the truth.
"They [ECB] don't have any proof against me. I don't know why they are saying this ("grave danger to cricket", etc). I will definitely be doing an appeal.
"The people trust me. I'm an honest man. I've been playing cricket with passion and love. I have done nothing wrong."
Westfield was sentenced to four months in jail in February after admitting a spot-fixing charge at the Old Bailey.
The 24-year-old also admitted an ECB charge of receiving a reward which could bring him or the game of cricket into disrepute and was banned for five years, although he can return to club cricket after three.
The ECB's disciplinary panel found Kaneria guilty on two charges - of knowingly inducing and encouraging Westfield not to perform on his own merits, and also of bringing the game into disrepute.
Despite the decision, it is still not clear whether the leg-spinner could play outside England and Wales, where the jurisdiction of his ban lies.
However, his hopes of playing back in his homeland would seem to be at an end after the Pakistan Cricket Board were one of the first signatories to the understanding.
Kaneria has played in 61 Tests in his career, taking 261 wickets. He made his debut for Essex in 2004 and took over 100 scalps in all forms of the game in the English summer of 2007.
