Voluntary organized team activities for the Vikings began Tuesday in Minnesota, but Peterson currently is staying home in Texas as planned, NFL Media Insider Ian Rapoport reports, per sources informed of the running back's thinking.
Peterson will receive a $250,000 bonus if he's at 90 percent of OTAs and minicamp. Peterson participated in OTAs and minicamps last year, but that was before he missed 15 games stemming from a no-contest plea on what the NFL called "an incident of abusive discipline" toward his 4-year-old son.
"It's up to Adrian, really," Zimmer said. "He's the guy you should ask ... We'd like all our players here. It's the voluntary time of year right now and it's his decision in what he wants to do."
