Simpson was suspended by the league for violating the substance abuse policy after he pleaded guilty to felony drug charge back on March 1. He is a former 2008 draft pick of the Cincinnati Bengals (pick No. 46 overall) who has grabbed 71 receptions for 1,004 yards and seven touchdowns over the course of his four-year NFL career. The Vikings signed Simpson to a one-year deal during the offseason.
It is unclear what Simpson's role be with the offense as he attempts to integrate with his new teammates during regular-season games, but he did impress coaches and fans with some strong performances during the preseason, so perhaps he could become an important part of the passing attack.
Reisner appeared in three games for the Vikings in 2012, but did not record any receptions during that time.
