The NFL has suspended 24-year old TE Shawn Nelson of the Bills for the first four games of the NFL regular season due to a violation of the league’s substance abuse policy.  Nelson played in 12 games (all starts) for the Bills as a rookie last year and he caught 17 passes for 156 yards (9.2 avg) with 1 TD grab.  This will hurt the Bills who were hoping that Nelson would improve and give them a threat from the TE position.
