Philadelphia Eagles quarterback Michael Vick had to cancel his book signing tour after a series of credible threats were made against Vick and employees at the Barnes & Noble stores where the book signings were to be held.
The Eagles' quarterback was scheduled to sign copies of his autobiography "Finally Free," at Barnes & Noble stores in Atlanta, New Jersey and Pennsylvania, but the March 26 appearance scheduled to take place in Exton, Pa., was listed as canceled on the book store's website.
Vick wrote his autobiography, "Finally Free," while in prison in Leavenworth, Kansas, which was released in September 2012.
In the book, Vick explained that he realizes the mistakes he made in life were very serious, but the experience has helped him "reclaim the narrative to his life."
"People are always going to have their opinions and feel the way that they do," Vick wrote. "You can't change it. The reason I'm writing this book is so people can have an understanding and not just go off of what they see on TV or what they heard, the picture that's been created."
Vick was released from prison in 2009 after pleading guilty to involvement in an interstate dog-fighting ring. Vick served 21 months in prison and in October 2012 admitted owning a dog, which was allowed after his probation terms expired last summer, according to USA Today.
When news of Vick owning a dog broke, he released a statement that detailed his desire to teach his children to develop a healthy relationship with animals.
"As a father, it is important to make sure my children develop a healthy relationship with animals. I want to ensure that my children establish a loving bond and treat all of God's creatures with kindness and respect," Vick said in a statement released at the time.
"Our pet is well-cared for and loved as a member of our family. This is an opportunity to break the cycle. To that end, I will honor my commitment to animal welfare and be an instrument of positive change," he added.
