Former NFL quarterback Colin Kaepernick is writing a memoir to be released later in 2020, and he's expected to share details of his time outside of football since 2017 in the currently untitled project.
"I've had a lot of questions surrounding what got me to the point of protesting," Kaepernick said to USA Today's Jarrett Bell. "Why did I do it? Why did I do it at that moment? Why wasn't it earlier in my career? A lot of questions surrounding what led me to that point.
"Which led me to wanting to share that story and give insight. So I think there's a lot of interest around it, but time will tell when the book comes out."
Kaepernick hasn't played in the NFL since the 2016 season.
The league arranged a private workout for him in November that 24-plus teams were expected to attend. However, due to a dispute over a liability waiver, the quarterback moved the workout to a local high school.
Though nothing came of the ordeal, Kaepernick still trains five days per week in anticipation of an opportunity to rejoin the league.
"My desire to play football is still there," he said. " ... I'm ready to go, I'm ready for a phone call, tryout, workout at any point in time. I'm still waiting on the owners and their partners to stop running from this situation. So I hope I get a call this offseason. I'll be looking forward to it."
