The NFL has upheld Simpson's three-game suspension stemming from a November DUI arrest, ESPN.com reports. Simpson is thus eligible to return to the Vikings' lineup for the team's Sept. 28 contest against the Falcons. Upon his return, his role will hinge on the health and production of his fellow wideouts, though presuming the availability of Cordarrelle Patterson and Greg Jennings, Simpson would slot in no higher than No. 3 on the team's depth chart at the position, at that time.
