Philadelphia Eagles quarterback Michael Vick continued his book tour on Saturday saying he would continue to stay "positive" and won't allow threats keep him from promoting his autobiography. A series of book signings for his book, "Finally Free," including one at an Atlanta book store on Saturday, had been canceled due to threats to Vick by store employees.

Vick received warnings of planned protests and his publishers refered to as "Credible threats" earlier this week before canceling appearances. Once the reported protests escalated into threats of violence against the retailers, Worthy Publishing, Vick and his family, decided to cancel the events," Worthy Publishing, a Tennessee-based Christian publishing company told CNN.

Vick signed books at an Atlanta-area church instead of the originally scheduled store, making an impromptu appearance that was set up in one day.

"That's a very small selective group of people who still have their own form of hatred," Vick said Saturday of those who made the threats, according to the Atlanta Journal-Constitution. "But you know, I think the most important thing for me to do is to continue to stay positive and continue to do the right thing because that's what's going to make a difference ... You gotta move forward."

All profits from Saturday's signings were donated to a charity that works with young males serving time in detention centers. The book itself chronicles the events around his conviction and his childhood in Virginia.
