So, this was mentioned by Ian Rapoport of NFL.com, and it's really barely a blip, but we'll put it out there anyway.
Defensive end Spencer Nealy, who spent most of the latter half of the 2013 season on the Minnesota Vikings' practice squad, will miss the first four games of the 2014 NFL season after violating the league's substance abuse policy. He was in training camp with the Vikings before the 2013 season after going undrafted out of Texas A&M, but was cut during Training Camp and was not re-signed to the practice squad until mid-November.
Nealy will still be eligible to participate in Training Camp and the Vikings' pre-season contests.
I'm pretty sure that Nealy was a long shot to be in the mix for the Vikings' on the defensive line. After this, it appears that he's gone from "long shot" to "no shot." The Vikings might keep him around, since he wouldn't count against the roster as long as he's suspended, but I would be surprised if that happened.
