The saga of Adrian Peterson in a Minnesota Vikings uniform may be at an end.

On Tuesday, the team said it is not picking up the $18 million option on the superstar running back’s option, making him an unrestricted free agent when the upcoming league year starts March 9.

The move comes as no surprise, as the Vikes keeping him at such a high cap number wasn’t tenable. Now, the team could conceivably work out a new, less expensive deal with Peterson leading up to Mar. 9, but indications point to him being able to test the market.

Peterson is coming off an injury plagued season that saw him rush for just 72 yards in three games, lessening his market value considerably. He did play all 16 games in 2015, rushing for 1,485 yards and 11 TDs, however his continued health will be of concern for any team hoping to gain his services.

Minnesota’s first round pick in the 2007 draft is the team’s all-time leader in carries (2,418),  yards (11,747) and touchdowns (97).
