(AP) — The Minnesota Vikings have declined to exercise their option for next season on running back Adrian Peterson. The Vikings all-time leading rusher will be an unrestricted free agent when the market opens next week. Had the Vikings picked up the option it would have been worth $18 million.

General manager Rick Spielman says the team will continue to investigate the possibility of bringing Peterson back. The 10-year veteran is coming off a meniscus tear in his right knee that limited him to 72 yards on 37 carries over parts of three games.
