"It was about me taking time off to heal," Harvin said to reporters. "Knew the level I wanted to play at and couldn't then. I'm refreshed and I'm ready to go."
The Bills announced Harvin will wear No. 11.
"Harvin was happily retired and investigating potential business deals when the Bills called to inquire if he was interested in rejoining the team, according to league sources," reported CBSSports.com's Jason La Canfora on Sunday. "The approach caught him totally by surprise; he had not been trying to maintain football shape or plotting any sort of return, but after mulling their offer for about 24 hours, opted to pursue it."
La Canfora, citing sources, added that "Bills senior vice president of football administration Bill Overdorf first broached the topic of Harvin's availability internally several weeks ago."
Harvin, 28, appeared in just five games for the Bills in 2015, catching 19 passes for 218 yards and a touchdown. He also rushed five times for 31 yards and spent time as both a kick and punt returner.
Injuries plagued Harvin once again, however, a consistent theme in his career. The talented but mercurial wideout played in just 28 games over the past four seasons, including just one game in 2013 with the Seattle Seahawks.
Harvin was named the AP Offensive Rookie of the Year in 2009 and looked like a promising, game-changing talent in his first three seasons with the Minnesota Vikings. But the injury bug bit him in 2012 and limited him in disappointing tenures with the Seahawks (2013-2014), New York Jets (2014) and Bills (2015).
Harvin also reportedly ran into issues with his teammates. According to NFL Media's Albert Breer, Seattle traded him to the Jets in 2014 because of anger-management issues. Similar concerns led Minnesota to deal him to Seattle in 2013.
The Bills offense has been dealing with injuries throughout the 2016 season, however, most notably to wide receivers Sammy Watkins and Marquise Goodwin and running back LeSean McCoy, so it could use the help.
Harvin was a dynamic talent who was dangerous in space and always a threat to score with the ball in his hands. If he's able to stay healthy and showcase some of the skills he displayed earlier in his career and the Bills can find unique ways to get the ball in his hands, Harvin can once again be a difference-maker.
